why do different materials reflect different wavelengths? Also does this mean that everything is actually colorless and color is a function of reflecting light only?

No. The colour of something is just what we call the light it reflects. Saying “that plant is green” is saying that it reflects green light.
The fact that colour is a function of reflecting light doesn’t make it any less real. Colour exists only in the brain, but a lot of very real things exist only in the brain.
