Gary Holland
 

I have attempted to recolor your Gary Holland image from the one you posted. The Palette.fm colorizing tool I have found works best on backgrounds. I usually color the background first, then after making sure the original and colorized images are the same size and ratio, I color the subject of the photo and copy and paste it over top of the colorized image. Depending on the quality of your source image, there are times when Palette.fm will adequately colorize the entire image. You will still need to tweak colors as the AI really just guesses. I wasn't sure what team Holland was on and so guessed at the colors, and surmised the team was the "Mounties" from the lettering. I presumed from the cap that it was the Vancouver Mounties. Whether colorized by hand or AI, neither method can really improve on the resolution or detail of the image. You might want to try a program like Remini if your images are too rough. It can sometimes use AI to fabricate missing data in an image.

Thank you
