Do you really say the word "ugly" for colors?

Native speaker’s answer

Yes. The word "ugly" can be applied to anything that is visually unappealing. "Ugly" colors are commonly those that do not match or compliment the colors in the environment they appear in or remind the speaker of unpleasant things. Ex: That dress she wore had such ugly colors. It looks like a trash bag. Ex: My mom insisted on using these ugly colors for my room, they remind me of a swamp.
