That is true, however it is not very much memory.

The number of pixels on the screen, multiplied by 3 or 4 bytes per pixel, is all that is needed for color.

For a 1280x1024 in black and white, you would use 1 byte per pixel = 1,310,720 bytes, or slightly more than 1 megabyte of RAM.

For the same screen in color, you would need (let's say) 4 times the bytes, thus 5,242,880 bytes, or just about 5MB of RAM.

Given that most readers have at least 128MB of RAM I think they would be willing to give up 4MB of RAM for decent color...
