In SL, color is composed of three elements (Red, Green, Blue) in values from zero to 1.0;
White is <1.0,1.0,1.0> and Black is <0.0,0.0,0.0> although you may see it as Black is <FALSE,FALSE,FALSE> because TRUE is 1 and FALSE is 0. LSL automatically accepts float numbers (with decimals) for integers and opposite. It's called "implicit typecasting."
Independent randomizing of red, green and blue is done by the use of LSL function llFrand(value).
Included is how to change prim color for both a single prim and a linked set.
Use the "//" comment slashes to activate the line you wish to use, and be sure to deactivate the line you don't want!

// To only change the prim this script is in - use this line
llSetColor(<llFrand(1.0),llFrand(1.0),llFrand(1.0)>, ALL_SIDES);
// To change the entire linkset - use this line instead
//llSetLinkColor(LINK_SET, <llFrand(1.0),llFrand(1.0),llFrand(1.0)>, ALL_SIDES); }
