This is most likely a color profile issue, because I can't reproduce it and nothing much else makes sense.

First try disabling color correction, and let us know if the problem persists.

If color correction is to blame, please locate and attach the color profile in use.

Yes, you're right and it seems to be a problem related to the color profile I was using. I think it's the profile that comes out of the box with the iMac (I can reproduce the issue on two different Macs), but forcing Chrome's color profile to sRGB fixes the problem and so does changing the system color profile to sRGB. 

I'm sending you the iMac default color profile.

Thanks for the feedback. We'll take a look.

The difference here is #212429 vs #202329, so #010100 -- depending on which path we take (solid color layers versus non-solid-color-layers), our math may be off by up to 1 pixel value (as is the case here).
