Complementary RGB Color Pairs

[Eric Chatonet]

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

20time

Best Regards from Paris,
Eric Chatonet
