RGB color accuracy? #569

I just tried to reproduce an image, and was struck by how different a neon green looked. It turns out that the color values passed to fill don’t seem to be that accurate – a color set as 0.5, 1, 0 actually shifts to 0.658 , 0.969, 0.298 – quite a difference! I tried changing the color space, but that didn’t make a difference. Also the color is the same in the exported PNG.

Is this user error, or do we just have to live with this inaccuracy? I can see https://github.com/typemytype/drawbot/issues/171 where things look like they’ve been fixed – possibly the macOS version makes a difference? I am on 14.4.1 (23E224), DrawBot Version 3.130 (3.130).
