# Why do objects reflect laser light?

Why do non-red objects reflect red laser light?

The color of things explained as "Objects reflect in the color that we see them, and absorb other colors."

But if to illuminate, say, a yellow thing with a red laser, one can clearly see the red reflected color.

How is this consistent with the fact that only yellow should be reflected by this thing, and red should be absorbed? It turns out that the yellow object is still able to reflect red.

I want to get more deep iformation about reflection of light.

When light is reflected from objects with a well defined colour, we perceive the reflected light as this colour because it reflects this colour. But the truth is that other wavelengths are also reflected, but less of it. The absorption of light is typically $$\alpha < 1$$ but still $$\alpha_{yellow} \gg \alpha_{green}$$ for example. Our eyes perceive the colour typically as that of the most dominant wavelength.
