Is it normal that colors bother me?

Don't ever drop acid.

Sensory overload. We all have different tolerance levels for external stimuli. For me, for instance, if I think I smell something overheating when I'm driving I have to turn off the radio, wipers, etc, anything that's making noise so I can focus on the smell to try to figure out what's causing it. If I'm looking at a large number of similar items I can't even pick out the one or few that look different from the rest. Because there are many of them all I see is a blur.

Some people are just more sensitive to stimuli. If it really bothers you, you might want to talk to a doctor or psychologist. (It COULD be a symptom of something.)

Colors bother me too. Namely black and brown. ; )

Watch the movie "Colors"

I love colours!! The more the better!

Not really.
