I re-discovered primary colours a few days ago. In school we were taught Red, Yellow and Blue, RYB, were the primary colours. The primary colours in painting, monitors and printing are different. Red, Yellow and Blue, RYB, are the primary colours in painting. Digital monitors have Red, Green and Blue, RGB, as the primary colours. In printing the primary colours are Cyan, Magenta, Yellow and Black, CYMK.
I experimented with these colours. I coloured OKTATA according to the 3 different methods of classification.
OKTATA in RYB – Red, Yellow, Blue
OKTATA in RGB – Red, Green, Blue
OKTATA in CYK: Cyan, Magenta, Yellow
I didn’t know about the primary colours in printing. This is new information for me.
When we were in school we learnt about primary colours especially in painting . However they did not teach us about the differences in printing. Perhaps information was more difficult to obtain 40 years ago than it is today.
