I try to learn more about colors and color theory. So far I have learned how to create a pallet of colors that match. But I could not find any information on clashing colors.
The only thing I was able to find was fashion related advice. But that was more like "do not mix pink and orange" and did not sound very scientific.
My guess is that two colors do clash if they have a similar (but different) hue and very different saturation and luminance.
Is there any theory on this? How can I find colors that really hurt the eye?
