input question: How to change the color of a shirt that you don't like.

output answer: You can use fabric dye to darken a color or patterned shirt. If you use black, and your shirt was yellow, the result may be a dark green or brown and may not turn out totally black. If your shirt has a pattern of reds and whites, and you dye the shirt blue, the reds will likely darken to purple and the whites to blue. Your dye may not turn out the color you expect, but it certainly can change the color of a shirt.
