Are the pull handle greys close enough to one of the other shades of grey
already defined or do we really need new colors?

[mdjones, 2017/03/13 23:43:39]

google_grey_700 would work but it lacks the alpha component. I'll ping UX.

[Theresa, 2017/03/14 00:01:44]

Depending on what Chris says, maybe we can use an existing alpha + black e.g.
4D000000 is ~30%. If nothing existing is close enough, let's at least push for a
round alpha number that's more likely to be reused e.g. 40%

#80FFFFFF we use in a few other places (e.g. light_mode_tint.xml) and we'll need
it for selection mode too (just asked Chris), so I think we could define
something like semi_opaque_white and re-use the color.

[mdjones, 2017/03/14 16:25:28]

Added semi_opaque_white and switched to using google_grey_500 for normal tabs.
