Please could somebody help me out with this. I have been asked to do this a few times before and decided to try and find out this time. I can't really see how you could do this but If it is possible please could someone tell me how to convert a grayscale image into a full colour image. Showing all pixels as a close match of what the colours would have looked like in real life. This is for a relatives sixtieth birthday and we would like to put a colour of her as a child on the cake and obviously one doesn't exist please could someone tell me if there is or isn't a way of doing it.

Thanks

I highly doubt that's possible. The opposite, converting colour to gray, is simple of course.
