Color systems

RGB

Red / Green / Blue

Additive color representation is used in displays lighted from inside.

RGB colors can be formed by using three separate LEDs or by passing the light stream through three different light filters. Drag red circle to perceive the color mixing process.

LAB

Lumina / A / B

LAB color space was designed to represent all colors visible to human eye. A is for green-magenta axis and B is for blue-yellow.

Lumina specifies the amount of light applied to the color.

You would not see any new colors because they are converted to the sRGB color space through some complex math formulas, but you can still play with mixing!
