I have been unable to find anything that tells what to put into the PHP scripts I am using to get the colors I want. The script goes from 0,0,0 (black) to 100,100,100 (white) and nothing I try looks like what I want. Anyone got any info on this?

PHP? If you are scripting in PHP, then you are most likely generating HTML, which requires RGB colors in hex (such as #000000 for black, #FFFFFF for white)

If you mean LSL, then the RGB colors are represented as a vector, with each value ranging from 0.0 to 1.0, so green, for example, would be <0.0,1.0,0.0>.

A great reference is the LSL Wiki page http://www.badgeometry.com/wiki/llSetColor

Hope this helps!

Another thing to remember, is that the colors are light spectrum, not like the colors you learned about in art class where blue and yellow are mixed together to make green. Light spectrum primary colors are RGB, you will notice that red and green make yellow.

Is that what you meant? There are a lot of HTML color chart conversion sites out there if you do a google...

I did a google with this search string:

HTML color conversion chart

and the first example was:

I hope that helps.

CODE


vector poundcolor2vector(string a)
{
    //Written by Strife Onizuka
    if(llGetSubString(a,0,0)!="#")
        return <0,0,0>;
    a="000000"+llGetSubString(a,1,-1);
    return <(integer)("0x"+llGetSubString(a,-2,-1)),
            (integer)("0x"+llGetSubString(a,-4,-3)),
            (integer)("0x"+llGetSubString(a,-6,-5))>/256;
}
