It is coming: a waveshare 7 color eink screen is $600 on aliexpress, 16 second refresh
If partial refresh comes more supported in open source, pictures could be drawn immediately with the b&w text, then refresh little by little to add color.
16 second refresh is a complete nonstarter for a note taking device. Its only good enough for a desk calendar screen. I'm not sure how much more can be done since these color e paper displays are basically a hack which doesn't scale well and degrades refresh rates as contrast from the ones I have seen.
There are a few "color eink" displays floating around in demos which are actually just an lcd with a matte layer over the top.
Real color eink is a hack too. Its multiple colors with the same magnetic polarity but in different sizes and the display is able to pulse the fields to select the color but its super slow and the colors can blend together a bit. All of the ones I have seen are 3 color and I imagine more colors make the issue even worse.
