No I can't. I consider redF() more canonical than red() (higher
precision, and QColor might become HDR in the future).
I could look at the pre-gamma-corrected values, but is that worth
keeping more variables around (or trusting the compiler to optimize
multiple calls to redF() and friends)?

(with apologies to Pino Toscano, PutHuhn and Albert Astals Cid, who came
up with this entirely on their own)
