Colour Challenge

How Colors Work on Screens

Computer screens create color by mixing three different colors of light: Red, Green, and Blue. This system is called RGB.
This is what 4 pixels on a screen look like close up. Can you guess what colour this would look like from further away?
Add maximum values of red, green and blue light together in the challenge below to see what colour they combine to make.

Each color can have different shades ranging from 0 (none) to 255 (full intensity):

With 256 values for each color, this creates 256 x 256 x 256 = 16,777,216 possible colors!

When all RGB values are similar, the color appears as a shade of gray.
