I suffer from deuteranopia and use the Spectrum extension in Chrome from Yehor Lvivski.

It's ok for switching between different color modes so I can see differences in them.

I am intrigued by the Enchroma glasses, haven't wanted to gamble $300+ on them yet.

Not colorblind myself, but I often use spectrum as a final pass to make sure any colors I've chosen for a UI aren't going to cause issues. I just hope it's decently accurate.

I'm also a very heavy F.lux user, so all my color choices have to be usable with an orange filter as well.
