Can you make a different colour?
By mixing primary color (red, blue, and yellow) you can achieve any color gradation you want

Well the computer runs off the red, blue, and green scheme. However, I believe the question was referring to making an entirely NEW color. And sadly that answer is no. The true basic color is WHITE from light. Black is the absence of light and, in the world of science, not considered a color at all. White light may be broken down into a spectrum you may remember from school. ROYGBIV (red, orange, yellow, green, blue, indigo, violet). When you look at an object, your eyes see the reflection of color that object cannot adsorb. For instance, when white light hits grass outside you see green because it absorbs all the colors but green, reflecting the green to your eyes, so the grass is technically every color butt green! Outside our vision lies the world's of Infrared and Ultraviolet ( the extremes of our spectrum). These types of light we cannot see, but are very damaging to our eyes. In a nutshell you must have light to have color and we are not equipped to see colors outside our white light spectrum. Sad....
