A person blind by birth cannot get dreams in color. In fact they cannot be even classified as black or white. There is no optical sensation. The neural networks in brain do not get developed for it.
They do have dreams, but they consist of sounds only. Its in the same way as you hear a radio....

No, they wouldn't. Visual stimulus is necessary for the wiring of the brain centers that process and interpret vision. The way the brain works is to develop, early in life, a huge number of neural synapses (connection points between neurons that are used in cell-to-cell signalling). As you grow and learn, these synapses are pared away to make the brain function efficiently, and that's the central basis of long-term learning. However, if the brain or any part of it fails to get infromation from hard-wired inputs, then that part of the brain will atrophy (at best, fringe areas of a cortical region might be adopted by adjacent cortical regions for different processes). But the take-away message here is that the brain needs visual stimulus in order to devolp the cortical regions that process vision. In the use-it-or-lose-it sense, the brain will not waste energy building and maintaining processes that aren't used. The optical cortex would never know how to function as an optical cortex in a person born blind

Blind (by birth) person never see the colors in real life. Then he don’t know what is the colors. Just imagination in black and gray colors only.
Blind(by birth) person dreams also in sounds only.

A very interesting question. There have been cases of people, blind from birth, being given sight through a corneal graft. I suppose the only people who could properly answer this question would be one of them.

Yes, but their dreams don't involve eyesight...their dreams involve the senses that they use, such as hearing, touch, and sniffing...for their mind cannot process eyesight, since they've never used their eyes to see.

I asked my blind friend from Africa what it was like to be blind and he said it could be worse, he could be black.
