A person wearing a blue shirt is standing in sunlight. What color (s) of light does the shirt reflect? What color (s) or light does the shirt absorb?

The shirt reflects most of the blue light that hits it, and

absorbs most of the light of all other colors.

That's a big part of the reason why, when you look at it,

you say "Oh! Oh! Look at that! That shirt looks blue!",

and why the shirt quickly gets a reputation as a "blue" one.

Im just a beginner but i know that the darker the the shirt is, the more sunlight it will absorb
