A lot of those color e-ink displays don't work like a LCD does, where you have R/G/B subpixels per pixel and get to mix final colors out of different intensities. Instead, a "7 color display" really means each pixel can only be one of 7 pixels. Another gotcha is that in some implementations, the screen refresh will go color by color, so for multi-color content, the refresh time is quite long (as in, you don't have a pixel flipping to blue and another flipping to red concurrently). This is just to manage expectations -- the result is still very cool.
