Apparently there is no such thing as pure blue paint, from an RGB perspective. How odd! They all have high green values. (from http://www.easyrgb.com/en/match.php )pic.twitter.com/6q6AQ1W8Fp

Hmm, thanks for the suggestion… I don’t know much about paint, but it seems to be hard to find actual color values online in a lot of cases
Colorimetry is hard. The mapping depends on way too many factors (e.g. what light you use), even if you assume sRGB on the RGB side. An unqualified RGB tuple is almost meaningless.

Colorimetry is hard, sure, but the difference I’m talking about is large enough that it doesn’t really matter.

The reason why there's no paint in pure sRGB corner colors is probably that it'd be too dark in normal lighting. If you only reflect a very narrow band of wavelengths as required, you're throwing away most of the spectrum. Things are always duller in reflective media.
