I’m an artist, and I’m looking for a few tools to help me

I have two things in mind that could help me a lot. I apologise if those are easy to find but I can’t seem to find anything using just google. I mostly find AI-art tools using prompt, which I’m not interested in.

First would be a tool to reverse search from a drawing. for example, I draw a pose, and a tool would find reference picture of the pose I drew.

Second would be something to enhance existing art. I’m colorblind, and something that would help immensely is a tool to color black and white paintings. Another interesting tool would be something that improves an existing drawing, for example by re-drawing it in a different style.

Any help is appreciated. Thanks
