Why can't we see objects in a darkened room?
In order to see, the eye must receive light; and darkness is the absence of light. Most of the objects we see around us are visible by reflected light -- reflected sunlight or reflected artificial light. Since darkness is the absence of light, there is no light in the darkness to be reflected from chairs, tables, or people to our eyes, and therefore we can not see these objects.

Why do you see certain objects as certain colors?
it depends on what you are talking about. If you are talking about relating certain shapes, letters or months to colors, then you most likely have synesthesia. If you are talking about physical colors, such as a pink shirt or a brown building, it is because of the reflection of light. Sunlight and most artificial lights are white, in other words, every color in the rainbow combined. Certain natural ad artificial dyes will reflect certain shades of that rainbow, and absorb the others. What we see is the reflection. So if a pair of jeans appears to be blue, then what you are looking at is the reflection of the color blue from the light emmited from whatever luminescent thing is shining upon it.
