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

A true recovery of the original colors from a single grayscale image is not possible: the chroma information is simply gone. What can be done is to create a plausible, visually convincing color version. That is what the software found tries to do, and is right that simple tools often work best on large, uniform areas but struggle with fine detail and complex edges.

Recommended workflow to get the best result for a treasured childhood photo (cake print):

  1. Scan the best possible source: high resolution (300–600 dpi for prints), save as TIFF, 16‑bit if the scanner supports it.
  2. Repair and prepare: remove dust/scratches, fix tears, balance levels/contrast and reduce noise. Cleaner input makes colorization far easier.
  3. Colorize: two paths — manual and AI. Manual: create color layers per region (skin, hair, clothing) set to Color blend mode, use masks and low opacity for subtlety. AI: tools like modern deep‑learning colorizers give fast, plausible results but may need local correction.
  4. Finalize for print: soft sharpening at final size, convert to the printer/profile the cake decorator uses, and do a proof print on paper if possible.

For easy experimentation try an automated model (for example DeOldify); for controlled, high‑quality work use manual painting in an editor (Photoshop Neural Filter colorize and blend modes are helpful) (). For an important heirloom, a professional restorer will produce the most reliable, historically plausible colors.

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

Infact, it seems to be possible. You can download a free trial of a program called blackmagic which is supposed to do it, i have not yet tried it though.

Wow, I'm impressed, it can't handle intricate shapes but it works well on large areas of color.
