What was your final verdict on colour? I recently picked up the QHY version of this sensor and am curious too. Using the below graph the sensitivities in each colour translate to 1:1.23:1:28 but that's at wild odds from what's been recommended here, so obviously that's not how it works. Also firecapture 2.7β is giving me 0-255 ranges instead of 0-100. The manual says you have to white balance it but only gives example numbers without saying if that's a recommendation, citing 161:128:255, which should like the ballpark ratios more in line with what I'd expect based on other camera usage. Poor English in the rest of the manual makes it hard to understand just wtf they mean about biasing colour.

I'm having all sorts of other troubles with capturing in firecapture on linux, but that's another story, and almost certainly related to it being the QHY camera...
