What is RGB Color Model?

RGB stands for "Red, Green, Blue". Each has a range from 0 to 255. If all the values are 255, we see white. If all values are zero, than we see black. If red is 255 but green and blue are zero, we see pure red. All (16,777,216) colors can be generated by mixing red, green and blue.

Experiment with the color tool below. Click on any color name to see its RGB values.

Black is the absence of light, so its RGB values are all zero (0,0,0) . White is the mixture of red, green and blue lights, so its RGB values are all at the highest point (255,255,255).

Red, green and blue are additive primary colors. They can not be produced by other lights. If green and blue lights are absent, we see red. Red is (255,0,0). Green is (0,255,0). Blue is (0,0,255).

Yellow, cyan and magenta are additive secondary colors, meaning that they can be produced by mixing red, green and blue.

Yellow is a mixture of red and green lights. Its RGB values are (255,255,0).

Cyan is a mixture of green and blue lights. Its RGB values are (0,255,255).

Magenta is a mixture of red and blue lights. Its RGB values are (255,0,255).
