260ms and 8:1, I think (maybe 9:1 ?).
Note, the 260/250 ms is a little misleading. That is the raw response time, but because of ghosting you almost never see that type of refresh done (unless it's a partial screen refresh). Most of the time the device does a "multi refresh" consisting of several stages every time you turn the page. It either inverts the current image, goes to a black screen, etc, and then refreshes the next page. There are typically 2-3 iterations of the response time that make up a single page turn (depending on the device's implementation).
Typical real world page turns with existing eInk are more on the order of 750ms.
So if the color has a 10ms shorter response time, you'll probably triple that for a single page turn. That would put it more on the order of 720ms vs 750ms for a page turn.
Assuming everything else is the same (multi stage refreshes, processing time, etc), which may not be true.
