HTML Color Codes

HTML colors are just the same as RGB colors but with the decimal
numbers converted to hexadecimal and then run together. So you can
calculate one from the other and don't need an array or lookup table.
Here is a function for doing the conversion.

function RGBtoHTML pRGB
    put item 1 of pRGB into r
    put item 2 of pRGB into g
    put item 3 of pRGB into b

    put baseconvert(r,10,16) into r
    put baseconvert(g,10,16) into g
    put baseconvert(b,10,16) into b

    return "#" & r & g & b
end RGBtoHTML

So you can do something like this:

answer color
put it into tRGBcolor
put RGBtoHTML(tRGBcolor) into tHTMLcolor

Cheers,
