I’ve tried processing E6 with it and it’s finicky if you’re trying to achieve high color accuracy. Due to the large surface to volume ratio of the SP-810 (even if covered) you lose several degC during the development. You could adjust the start temp so that the average (of the start/end) is where you want it to be but it creates some issues and I get color shifts. So I would not recommend it for color although it may be workable depending on your expectations.

Otherwise it’s absolutely perfect for B&W.
