Just one more drop #blood

u/SockTaters

Huh, the drops look red on my iPhone but brown in Chrome on Windows
u/tomxor

It's going to be a CSS parsing difference for sepia(.6 in Webkit. Gecko and Blink's CSS parser allow values involving syntax with parens to be interpreted without explicitly closing e.g hsl(0 0 50 is another. AFAICT the spec doesn't explicitly say this is required, but nether does it say it's ok to not close parens.
