I could do them by hand but then i lern nothing.
I want to split cmyk on 2 pages.

How do i get every combination? (so not permutions this time).
The order doesn't matter, so
page1 - page2

CM - YK
is same as
MC - KY

I hope you understand what i mean.

edit:

for rgb this will be all possibilities:
r    gb
rg    b
rb    g
