Hi folks,
How can we calculate the complementary color of a given color?

I'm trying to write a macro for calculate the analogous and complementary colors
for a given value, something like what you get on this page:

http://www.yafla.com/yaflaColor/ColorRGBHSL.aspx

but for the moment I'm blank as working with color wheels in pov-ray rgb
vectors.

Here are a staple in Spanish to review the theory of colors, the images show the
relationships between complementary colors.

Thanks in advance, the pov-ray links to color wheels rusted time ago

In the colors.inc file, there is a macro to convert from RGB to HSV. The 
hue returned is in degree going from 0 to 360.
Convert your colour from RGB to HSV, add 180 to the hue and convert back 
to RGB and you're done. The saturation and brightness will stay the same.

Thank you very much for your help. My eyes, harmed by random combinations of
colors pink + lime green thanks you too.
