Senior Project Design problem "converting images from gray scale to colored". !!!!

i'm working on a senior design project and I'm stuck in it. the project is about converting a gray scale image into colored image with no reference images, Just the gray scale image. the idea that I'm working on is extracting the three layers "Green, Red , Blue" out from the gray scale image. Is there any possibility to do it, cuz I can find no way to finish the project. please advise me.

If you had a database already built of feature descriptors for objects, and "typical" colors for those objects, then you could match the objects in the image and colorize what you found with the typical colors.

The easiest way to build such a database would be to use a whole bunch of reference images, though.
