How to change the color of an object in a photo - MaxPixel - 05-25-2022

I'm new to Gimp and photo-editing. I took a photo, and there's an unpainted white panel that's distracting. Here's the photo: https://imgur.com/8xVe5Xv

Is there a way to add something to the panel?

Is there a way to change the color of the panel to black or grey?

Since the panel is a 3d object, it would not have uniform level of black or gray. Also, it would not be perfectly black since no real-life object is perfectly black.

Any uniform color is going to show out. My suggestion:
  • Create a square layer (side size: about the height of the panel)
  • Set the brush to "Dissolve" mode and medium opacity
  • Fill it with random strokes of colors
  • [attachment=7976]
  • Use the Perspective tool to map the layer on the square
  • [attachment=7977]
  • Use Contrast to reduce contrast so the panel blends better
  • Use a layer mask to left the arm show
  • [attachment=7978]

You can completely get rid of the panel by using the heal tool with a custom brush

Just by pulling the exposure back in 'color' after selecting the board, you can keep the 3D look, shadows etc.
