Adobe Photoshop Color Tutorials

Every-thing we see is a combination of red, green and blue colors. When we look at a rainbow, all our eyes see are red, green, and blue. When we see all three of those colors in a balanced amount , we see white light. The more light there is, the brighter it is; the less light there is, the darker it is. We often call a low level of white light gray, so that's what we'll call a balanced amount of red, green, and blue. When they aren't balanced, we see color. Photoshop works the same way.
