1) What are some colors that affects humans?

Humans can see light that is in the range of 400-700 nanometers in wavelength. We see that light as colors from red to violet. So in the sense that we can see them, all those colors (red, orange, yellow, green, blue, violet) affect human beings.

A lot of artists, interior designers, and architects also believe that different colors have different effects on our moods. Painting a room a cool blue, for example, might help calm people down. Painting it red might get them excited and motivated.

2) How does the brain interpret the color red?

The brain figures out what color things are by comparing how much light there is at different wavelengths. Let's say you are looking at a sunset. During the sunset, there is a lot of light at 400 nanometers, but not much at 600 or 700 nanometers. Your brain would interpret that as red.

3) What makes the eyes see certain colors?

Well, I guess I explained that already in the last question. Every color you see has more light at some wavelengths than at others. So your brain compares the amount of light and that determines the color.

4) How does the brain and eyes interpret things that are reflected from

Everything you see, you see because light from the sun, or from a lamp, is reflected from it. A perfect reflector, like a mirror, reflects back all the light that hits it. But most things aren't perfect reflectors, so they only bounce back some parts of the light that hits them. That's what can make them look colored.

I said that everything you see is because of reflected light. That's not completely accurate - things like your computer monitor, lamps, or even the sunset you see directly. But you see pretty much everything else because it reflects light.

5) Does a childs brain and an adults brain interpret colors differantly?

Children's eyes are capable of figuring out what color things are at a very early age (by 4 weeks). Scientists are still studying how much, and how well their brains use that information. Nobody knows for sure.

6) In your research have you found any colors that are harder to interpret?

If so what colors?

7) Do you feel that color psychology works and in later days will have a greater impact and understanding?

Yes! Definitely. Many of the electronic devices you probably use have benefitted from an understanding of color vision and they will only get better as more color science in used to improve them. In the coming years, colors on digital cameras, computer monitors, and color printers will probably improve a lot because scientist are getting a better understanding of how humans see color.

Studying color could also help us understand philosophical questions. For example people often wonder whether one person's red is the same as another person's red (How do I know that what looks blue to me doesn't look red to you?). Color science can help to answer those kinds of questions.

8) W hat are some of the unusual things you have found in your research?

I don't know if it's unusual, but one of the most suprising things to me is that our vision is constantly adapting to the light around us. I'm sure you've noticed that when you go outside into the sunlight, it's much brighter than it was inside, but your eyes adjust in just a few seconds. Your vision adjusts in many other ways too. Try out this demonstration:

It shows you how color vision adjusts to whatever you are looking at.

I hope that I answered your questions. As I mentioned in the beginning, there are a lot of people that think that colors affect our mood, or that they show something about our personality. That could be true (I personally would get pretty irritated if I had to work in a room with bright red walls!). Scientists have tried to measure the effect on people's mood by seeing how colors affect their blood pressure, heart rate, and things like that. From what I've read, though, they don't get very consistent results: one test subject might have an increased heart rate when they see red (or some other color), but another might not.

One explanation could be that people's emotional reaction to color could just be because of their experience with that color (maybe they had an accident where they bled alot and were in a lot of pain).
