Color in LSL
Color in LSLLSL 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
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>;
Useful Snippets
Useful functions for storing/retrieving color and alpha values to/from integers
integer ColorAlphatoRGBA(vector color, float alpha) { return (((integer)(alpha * 255.0) & 0xFF) << 24) | (((integer)(color.x * 255.0) & 0xFF) << 16) | (((integer)(color.y * 255.0) & 0xFF) << 8) | ((integer)(color.z * 255.0) & 0xFF); } vector RGBAtoColor(integer rgba) { return < ((rgba >> 16) & 0xFF) / 255.0, ((rgba >> 8) & 0xFF) / 255.0, (rgba & 0xFF) / 255.0 >; } float RGBAtoAlpha(integer rgba) { return ((rgba >> 24) & 0xFF) / 255.0; }
