Color in LSL

Color in LSL

LSL has its own special format for color. LSL uses a vector to store color. Unlike traditional RGB where each channel is 0 -> 255, LSL's color channels are 0 -> 1.

Format: <R, G, B>

• float x Red value [0, 1]
• float y Green value [0, 1]
• float z Blue value [0, 1]

Examples

<lsl>vector white = <1.0, 1.0, 1.0>; vector grey = <0.5, 0.5, 0.5>; vector black = <0.0, 0.0, 0.0>; vector red = <1.0, 0.0, 0.0>; vector green = <0.0, 1.0, 0.0>; vector blue = <0.0, 0.0, 1.0>; vector yellow = <1.0, 1.0, 0.0>; vector cyan = <0.0, 1.0, 1.0>; vector magenta = <1.0, 0.0, 1.0>;</lsl>

Useful Snippets

Useful functions for storing/retrieving color and alpha values to/from integers
