I've gone with accurate; that's the strategy throughout phobos.
Yeah, I agree. For fast on the CPU you want to use simd, and
maybe one register for red, another for green, using saturating
instructions, doing it differently on ARM vs x86 etc...
Besides, an accurate reference implementation is a good starting
point and also very useful for unit testing a faster
batch-oriented version later on.
Here's a PR to see where I'm at:

Nice start. Most libraries use US-English "color", though. I
guess phobos should try to be internally consistent (pick either
UK or US vocabulary).
