The current color EINK technology is just the black and white eink we are familiar with, with a color filter overlay on the screen to tint the white particles under it. Because this blocks a significant amount of light (absorbed by the color filters), it will never have saturation anywhere near what you get from light-emitting displays (LCD, CRT, OLED, or plasma).

However, there are different eink-like passive color display technologies that may have better color saturation, but the ones so far available appear to have a very narrow viewing range that shows this color saturation (off axis viewing has very low saturation).

Technology has some catching up to do to bring us the eink color technology with the display quality we crave, but it WILL happen (right after we invest a significant amount in a lesser-quality passive-color device).
