--card script --
on MakeColor pPos
  local tNum
  lock screen
  put 0 into tNum
  repeat with i = 1 to 18
    set the backColor of fld i to libColor_Convert(tNum & comma & pPos &
",100","RGB","HSV")
    add 20 to tNum
  end repeat
  unlock screen
end MakeColor


--the stack script is an impressive library of conversions, etc.

I can send you a copy of Eric's stack or you can get it from SoSmartSoftware
