Color and the psychological effect
Indeed, colors have its psychological effect, each color has its private frequency, and this frequency affects our eyes. When we see a color, the frequency of that color is transferred through the eye into brain and affects brain cells. Colors have an effect on our personality and we can analyze personality of people if we know their favorite colors. In fact there is no documented scientific study about effect of color on human but only notices by scientists. God says 
And whatsoever He has created for you on the earth of varying colors [and qualities from vegetation and fruits (botanical life) and from animals (zoological life)] Verily! In this is a sign for people who remember.)(Sûrat An-Nahl- verse 13). Scientists observed a clear Physiological effect for the Red as being exposed to that color for long time may increase blood pressure , also it has an effect on glands of our body ,therefore it activate body cells and increase its energy , if we decrease the red color to be pink so effect will decrease .
Researchers confirm that this color affect our immunity system, our immunity increases if we are exposed to orange for long time. That may be because vibrations of immunity cells agree with frequency of Orange.
Today, researchers link between yellow and activity of brain cells, also yellow increase pleasure, some researchers link between yellow and fear and death , but it is not based on any kind of scientific proof.
Some researchers believe that green is useful for heart, and it helps to deep breathing. Also it helps in rebalancing all cells. Green makes people happy so that we find doctors in surgery rooms wearing green to make their patients happier and more optimistic.
It helps in reducing blood pressure, and it has an analgesic effect on body. It activates pituitary gland, also it helps to sleep deeply and it strengthens marrow of bones. Some people believe that blue helps in creativity.
It helps in calming anger. This color is the most important one in emotional stability and changing life of people.
Researchers believe that this is the color of stability also it is the color of nature as soil is brown so that it reminds us with simplicity and humility.
This is a negative color and it is not useful for treatment. Some people see black as the color of dignity; others believe that black refers to sadness.
Islam believes that all colors are important and they complementary with each others.
It brings peace and rest and erases desperation, so that people who are in desperation may wear white clothes to decrease that desperation.
Colors are repeated in Qur'an exactly as number of colors in spectrum
We know that the visible light spectrum consists of seven colors which are (Red, Orange, yellow, green, blue and violet), we have to mention that Qur'an mentioned colors seven times in the following verses:
1. (And whatsoever He has created for you on the earth of varying colors [and qualities from vegetation and fruits (botanical life) and from animals (zoological life)] Verily! In this is a sign for people who remember.)(Sûrat An-Nahl- verse 13).
2. (There comes forth from their bellies, a drink of varying color wherein is healing for men. Verily, in this is indeed a sign for people who think.)(Sûrat An-Nahl- verse 69).
3. (And among His Signs is the creation of the heavens and the earth, and the difference of your ********s and colors. Verily, in that are indeed signs for men of sound knowledge.)( Sûrat Ar-Rûm- verse 22)
4. (See you not that Allah sends down water (rain) from the sky, and We produce therewith fruits of various colors)(Sûrat Fâtir –verse 27).
5. (And among the mountains are streaks white and red, of varying colors and (others) very black.)(Sûrat Fâtir –verse 27).
6. (And likewise of men and Ad-Dawâbb [moving (living) creatures, beasts], and cattle, are of various colors. It is only those who have knowledge among His slaves that fear Allah. Verily, Allah is All-Mighty, Oft-Forgiving.)(Sûrat Fâtir –verse 28).
7. (See you not that Allah sends down water (rain) from the sky, and causes it to penetrate the earth, (and then makes it to spring up) as water-springs, and afterward thereby produces crops of different colors, and afterward they wither and you see them turn yellow; then He makes them dry and broken pieces. Verily, in this is a Reminder for men of understanding.)(Sûrat AZ-Zumar- verse 21).
We ask a question for people who may think that Qur'an is a human made: Colors are repeated in Qur'an exactly as number of colors in spectrum, is it just a kind of coincidence or it is the power of almighty God?
Color is a method to think and remember
My dear, have you ever think about flowers and its wonderful colors? Please, read the previous verses again as God made a link between color difference and remembrance, god says :( In this is a sign for people who remember.) And he made a link with thinking, he says :( in this is indeed a sign for people who think.)Also God made a link with science as color difference argues scientists to study this phenomenon to believe in the greatness of the creator, God says :( in that are indeed signs for men of sound knowledge) .at the end of the verse God told us that color difference is to remind people who have brains, God says:( in this is a Reminder for men of understanding).
Researchers believe that the phenomenon of color difference is amazing, how can flowers to organize its colors in a great harmony? Who made that? How can it receive instructions to produce this fantastic coordination?
Answer is so simple, God says :( He is Allah, the Creator, the Inventor of all things, the Best former. To Him belong the Best Names. All that is in the heavens and the earth glorify Him. And He is the All-Mighty, the All-Wise.)(Sûrat Al-Hashr- verse 24).
The idea of healing by colors depends on that color is a frequency of an electromagnetic wave, so by using a specific color we can modify frequencies of the body. each one has an electromagnetic field around his or her body , this field get affected by colors of clothes and all surrounded colors, so that when we are in a garden we feel with psychological rest because of the effect of the reflected frequencies of green color on our body.
Here we have to remember a great verse to remind us with the effect of green nature on our life, God says :( Is not He (better than your Gods) who created the heavens and the earth, and sends down for you water (rain) from the sky, whereby we cause to grow wonderful gardens full of beauty and delight? It is not in your ability to cause the growth of their trees. Is there any (God) with Allah? Nay, but they are a people who ascribe equals (to Him))( Sûrat An-Naml- verse 60). It is nice to mention that some researchers in west treat their patients (especially with depression) by looking at plants and green nature.
What may happen if colors disappeared?
Colors are just a grace from our creator be he blessed and exalted and we have to thank him for that , if the world is only in white and black , people may be infected by depression and fear . Colors are a source of happiness and optimism. as a method of getting confessions form prisoners , they put the prisoner in a room with one color (red for example) so that he became not able to stay for a long time in that room and he might infected by depression which leads him to confess with all what he knows to end that situation . So imagine if we are in one color world, it would be as a big prison. Thanks God for your graces.
Yellow between happiness and death
God says :( and afterward they wither and you see them turn yellow; then He makes them dry and broken pieces) (Sûrat AZ-Zumar- verse 21)
God mentioned yellow five times in Qur'an, some times to refer to happiness and other times to refer to death, in other word the stage before death. Pale yellow refers to death and end of life and bright yellow refers to joy and happiness, God says :( It is a yellow cow, bright in its color, pleasing to the beholders)(Sûrat Al-Baqarah- verse 69), read again the verse (pleasing to the beholders.)So that yellow is a pleasing color.
Also God says :( It is He Who sends down water (rain) from the sky, and with it We bring forth vegetation of all kinds, and out of it We bring forth green stalks)(Sûrat Al-An’âm- verse 99)researchers confirm that green is a sign for life , God says:( and seven green ears of corn, and (seven) others dry)(Sûrat Yûsuf- verse 43). So green is a sign for life and pale yellow for death.
People in heaven are in green clothes
God says about clothes of people in heaven: (and they will wear green garments of fine and thick silk) (Sûrat Al-Kahf- verse 31). Also he says about cushions in heaven :( Reclining on green cushions and rich beautiful mattresses.)(Sûrat Ar-Rahmân- verse 76)
We can realize from reading Qur'an that green is the color of heaven and also we have to realize that prophet Mohamed (peace be upon him) told us that heaven has eight doors, is there a relation between green and number of doors in heaven?
Green is repeated eight times
God mentioned green in Qur'an eight times. Read the following verses:
1. (It is He, who sends down water (rain) from the sky, and with it we bring forth vegetation of all kinds, and out of it we bring forth green stalks, from which we bring forth thick clustered grain.)(Sûrat Al-An’âm- verse 99).
2. (and seven green ears of corn, and (seven) others dry)(Sûrat Yûsuf- verse 43).
3. ( and of seven green ears of corn, and (seven) others dry,) (Sûrat Yûsuf- verse 46).
4. (and they will wear green garments of fine and thick silk)(Sûrat Al-Kahf- verse 31).
5. (See you not that Allah sends down water (rain) from the sky, and then the earth becomes green? Verily, Allah is the Most Kind and Courteous, Well-Acquainted with all things.)(Sûrat Al-Hajj- verse63).
6. (He who produces for you fire out of the green tree, when behold you kindles therewith.)( Sûrat Yâ-Sîn- verse 80).
7. (Reclining on green cushions and rich beautiful mattresses.)(Sûrat Ar-Rahmân- verse 76).
8. (Their garments will be of fine green silk and gold embroidery.)(Sûrat Al-Insân- verse 21).
Is it a kind of coincidence that number of doors on heaven is eight and green was mentioned in Qur'an eight times?
Black is repeated seven times in Qur'an
Prophet Mohamed (peace be upon him) told us that hell is dark and black, we have to draw your attention that God mentioned black seven times in Qur'an, this is the same number as number of doors of hell, God says And surely, Hell is the promised place for them all.*It (Hell) has seven gates, for each of those gates is a (special) class (of sinners) assigned.)(Sûrat A-Hijr- verse 43-44). Please read the following verses:
1. (and eat and drink until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night),)( Sûrat Al-Baqarah- verse 187).
2. (On the Day (Day of Resurrection) when some faces will become white and some faces will become black)(Sûrat Âl-‘Imrân- verse 106).
3. (As for those whose faces will become black (to them will be said): "Did you reject Faith after accepting it? Then taste the torment (in Hell) for rejecting Faith.") (Sûrat Âl-‘Imrân- verse 106).
4. (And when the news of (the birth of) a female (child) is brought to any of them, his face becomes blackish, and he is filled with inward grief!)(Sûrat An-Nahl- verse 58).
5. (And among the mountains are streaks white and red, of varying colors and (others) very black.)(Sûrat Fâtir –verse 27).
6. (And on the Day of Resurrection you will see those who lied against Allah (i.e. attributed to Him sons, partners) - their faces will be black)(Sûrat Az-Zumar- verse 60).
7. (And if one of them is informed of the news of (the birth of a girl) that which he sets forth as a parable to the Most Gracious (Allah), his face becomes blackish, and he is filled with grief!)(Sûrat AZ-Zukhruf- verse 17).
What a great harmony , God mentioned green color eight times in Qur'an and prophet Mohamed (peace be up on him)told us that number of doors of heaven are eight also, God mentioned black color seven times in Qur'an and he told us that number of doors of hell are seven), is there any blind coincidence to do such thing?????
White is the most mentioned color in Qur'an
White was the favorite color for prophet Mohamed (peace be upon him), he used to supplicate God by saying O' God, please purify me from sins as the white clothes are purified from dirt), also white is a sign of success in day of resurrection. God says :( On the Day (Day of Resurrection) when some faces will become white and some faces will become black; as for those whose faces will become black (to them will be said): "Did you reject Faith after accepting it? Then taste the torment (in Hell) for rejecting Faith."*And for those whose faces will become white, they will be in Allah's Mercy (Paradise), therein they shall dwell forever.)(Sûrat Âl-‘Imrân- verse 106-107). So, colors determine our destination in day of resurrection according to our deeds to drive us to heaven or to hell. We received a notice from a French psychologist who mentioned that doctors in surgery operations room wear green; this color is Comfortable for the eyes of doctors. Also they may wear blue to get relaxing during operations.
