It isn't traditional eink if it doesn't use a filter for colour, even if called eInk.
It's made by the E Ink company but isn't eInk, it's Advanced Color ePaper (ACeP™).

In Gallery 3, the black and white update time has been improved to 350 milliseconds (ms), the fast color mode is 500 ms, standard color mode is 750-1000 ms and best color is achieved at 1500 ms. This is a substantial improvement over the first generation of E Ink Gallery, which had a black and white update time of two seconds and color updates of ten seconds. In addition, Gallery 3 will have an improved resolution of 300 pixels per inch (ppi) versus the earlier 150ppi and an operating temperature of 0-50 degrees Celsius, on par with black and white eReaders. E Ink Gallery 3 will also support pen input in black and white, with an addition of several other colors and an update time of 30 ms. E Ink Gallery 3 will be featuring E Ink’s new ComfortGaze™ front light, which offers a blue-light safe viewing experience.

They are coy and don't say how many mono shades or colour hues it does.

I'd take any info on other sites with a bucket of salt.
It's using four layers of Cyan, Magenta, Yellow, and White (black) so will be considerably dimmer than real eink mono, but brighter for same light as the higher saturation filtered eink.
It's very slow at about 3/4 to 1 second, or 1.5 seconds for full colour. Even fast mode colour is 1/2 second. Mono is a little slower than 1/3rd second.
