I was always under the impression that CMY were the color complements

complements or opposites to RGB
What are these "other complements or
opposites to RGB"? I have a friend who is a
photographer. He was taught, and always
refers to, Blue, Red, Yellow filters on his
colour enlarger but, when I looked, these
were simply unusual names for Cyan, Magenta,
Yellow.
does anyone know why this situation is? are there two rights or is
someone wrong?
What you describe is really two *wrongs*, as
human perception uses something close to Lab.

What this Wikipedia article shows is a
number of different colour wheels. These
are mostly close to Lab (human perception)
where colour opposites are Green/Red and
Blue/Yellow.
Stop trolling.
