Bootstrap button class .btn-primary fails color contrast

[nickbristow]

The blue "RSVP for 18F Demo Day" uses the .btn-primary class from bootstrap which has,
background - #428bca
Text - white

This fails 508 color contrast at 3.63:1 Which is just below 508 standards.

The hover state has,
background - #3276b1
Text - White

Which passes 508 but not AAA.

Fix Suggestion
Override bootstrap class with new background colors
Normal state
Background - 2e6ca2

Hover
Background - 255782

I think this is moot, with Demo Day past? To the extent we need to revisit the site for 508 color contrast issues, it seems worth doing as part of a larger touch-up, which I think we're in a position to do.
