Answer 1

Bright objects are bright because they reflect most of the light falling on them – this reflected light is what we see as brightness (unless the object in question shines on its own, of course, like a lamp). Dark objects are dark because they don’t reflect that light, absorbing it instead (light has to go somewhere, it can’t just disappear without trace). It’s really as simple as that. This applies to clothing as well.
