Show warning when pasting an image to an image with unsupported color mode
Operating System: All
Description of the feature
Have an option to show a warning when a source image is pasted onto an image which has a color mode that the source does not support, e.g pasting a RGB source image onto an Indexed destination.
Perhaps have a button labelled "Paste Anyway" which pastes the image and change colors to their nearest color, and a button labelled "Switch to RGB" which switches the image to RGB mode. This warning will not show if the source image only contains colors that are in the color index
Use cases
This will prevent users from accidentally losing colors without knowledge, especially if the color it gets mapped to is very similar
