give some feedback that some colors are not available in indexed images

Link to original bug (#154091)
Description
Open up a GIF image, the indexed palette of which is entirely allocated and does not include black. Select black as the foreground color, pick a paintbrush, and try to draw something. I spent 20 minutes trying to figure out why it wasn't black. I wish it had told me something like, "some color substitutions are being made, because this image has an indexed palette".
