All right, so once we have the basics working, we'll need a way for the user to say what color mode they want to be in. Due to the image formats the back end supports, there are actually a lot of choices here. This includes:

• Black and white
• Grayscale (8-bit)
• CGA
• 1, 2, and 4 bit color (but not set colors)
• 256 color
• 5, 6, and 8 bit per channel (15, 16, 24 bit total)

This is really getting the basics up and running, not all the options at once, but having the interface there early will be important before full-color gets too baked in.
