Hi Stephen and Jim,

Seeing this thread when waking up.
Yes, Monte lib is invaluable for converting colors from/to RGB, HEX, HTML, CMYK and even Pantone :-) 'Harmonized Colors' is not on my website but on RevOnLine (User: So Smart Software) I think also that Marielle has done nice stacks in this field: see http://revolution.widged.com/stacks/index.php?lastadded=added%20any% 20time

Best Regards from Paris,
Eric Chatonet

I would like to calculate the complementary color from an inputted color trio.

For instance I know that these two sets of two colors are complementary.

This is not a direct answer to your question, but some examples of
outstanding color tools you might be able to use.

--Eric Chatonet  -- using libColor
HSL ColorsHarmonized.rev

--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

0,128,128
128,0,0

255,0,0
0,255,255

represented in binary, they look like this


00000000,10000000,10000000
10000000,00000000,00000000

11111111,00000000,00000000
00000000,11111111,11111111


YELLOW and GREEN look like this

255,255,0
0,0,255

11111111,11111111,00000000 yellow
00000000,00000000,11111111 green


some of these look like simple inversion but I don't think it's quite
that simple.

I'm sure someone has worked this out...
thanks
