I'm going back to square one to make sure my colors are stable across as many interwebs systems as possible. I even bought a new monitor for my collection. Long story short: I want to live in the heart of sRGB.
But, I already hit a snag. I open AE, working space sRGB IEC61966-2.1, I put down D70000 red. Looks like it should. I open my latest version Mac Digital Color Meter. I take a look. It says D70000. Sweet. Just for kicks, I turn the working space to None. I use the meter again. D70000. Awesome. I export a .mov and check the color: D70000. This is great! Remember Tony the Tiger?
By the way, I'm using the (Sierra) Mac sRGB IEC61966-2.1 for my profile. I haven't calibrated or profiled my new monitor yet because I just want to see how things work out of the box.
SNAG TIME: Ut oh: I create a web page with a style sheet with background color D70000. But the Digital Color Meter says: FF0000!!! This happens on both Safari and Firefox
The old answer would have been something like this: The browser is doing gamma correction. But that's the old answer because Apple has switched to 2.2 gamma now.
Does anybody know the new answer? What explains the discrepancy? On the one side we seem to have Adobe and OSX, on the other we seem to have Safari and Firefox.
