Hi Toni,
can you please tell me if the following idea would be possible to implement and, if yes, how much effort do you think it would take to add this to WinUAE (and if you'd be willing to do it)?
Add the option to replace every pixel (in every drawn frame) of
one specific color with the color of the respective line of a given "mask"-picture that we can select - a picture like one of these ("copper"-like backgrounds taken from Turrican II):
So that we'd be able to replace the one-color backgrounds of e.g. Giana Sisters or Turrican I:
...with the multiple colors from the selected "mask"-pic.
So that the result would look about like this:

this Lemon thread)
This feature could enrich games with one color backgrounds.
There could be a limit set for the lines to be affected so that the hud at the bottom wouldn't look weird in case it has some pixels of the same color as the playfield's background.
The implementation could be an enhancement of the existing mask-/overlay-feature in the filter settings where only the pixels of one specific color would be affected by the mask.
