Thanks to all who responded.
I was turned onto a lot of information about color.
I guess the upshot is that a simple compliment - literally - will do
what I wanted - subtracting 255 from each part of the color array.
This is what I came up with:
FUNCTION complimentColor pTrio
REPEAT for each item tITEM in pTrio
put abs(tITEM - 255) & comma after tOut
END REPEAT
delete last char of tOut
return tOut
END complimentColor
Obviously there are many color reference systems out there that can
provide great color combinations... especially the one at
http://wellstyled.com/tools/colorscheme2/index-en.html
For those who do not want to bother to download a big stack just for
the matter of a few script lines
here is the script of btn "complementary colors" that at least gives
you a hint how to proceed to find out
complementary color triplets:
"on mouseUp
set the cursor to watch
put the milliseconds into Start
put the imageData of image 2 into iData
put 0 into counter
repeat for each char C in idata
add 1 to counter
put numtochar(255 - chartonum(C)) into char counter of idata
end repeat
set the imageData of image 2 to iData
put the milliseconds - Start into fld "test"
end mouseUp"

Wilhelm Sanke
