I think that would rule it out for the purpose of this project - the demo in their introduction video[0] shows that it flashes multiple colors for ages during this long refresh. I imagine that could be very confusing for someone whose short-term memory might not last that long.
Yeah, a black and white version would probably have been fine. Somewhat frustratingly they don't seem to have a 7 inch greyscale one though, only colour versions! Maybe they used to but stopped selling them?
