I'm sure I've read that before and it gave me a starting point for mixing paints. Technically, people will argue that PC10 (and later PC12) were not "paints" per se, similar to arguments about what "color" clear doped linen was.

I was surprised at how much red could be added while affecting the PC10 very little. In terms of glossy, I like the way my mixture looks under a couple of coats of Nelson's Flat Clear. It's also worth noting that when first applied it looks a bit greener and becomes browner as it dries.
