When trying to simulate the compositing that a browser currently does, and you have multiple transparent colors, it is important to ensure that you take all colors into consideration. Most...

Turns out that what I suggested only works when the background is white. So, I clearly don't understand how the `opacity: 0.6` is distributed across already transparent colors. I'd be...

Okay, this makes sense, and I do remember seeing that in the spec. I apparently had a bug with my premultiplication handling in composition which broke my `source-over` being associative...

That is not what I see at all in Safari TP, I get white on my Display P3 monitor. Unless there is some other special feature you have enabled that...

I should probably state that everything I've said only applies to colors, not images and such. I've done no comparisons as to what any browser does with images or videos.

One other clarification, my statements are also based on the idea that a Display P3 monitor is using a Display P3 color profile. If you were using a different color...

I'll duplicate this here as well in order to get feedback: Just an overall description of how the current prototype is laid out. I think I'm ready to discuss the...
