Color contrast - ePortfolios
Color contrast - ePortfolios

Fixes: CNVS-15615

Small UI tweak to increase foreground-
background contrast in ePortfolios section.

This was one of those amazing tickets where
most of the bugs were fixed by simply changing
one background color value. Yay!

IMPORTANT: This ticket is only for the high-
contrast UI. To enable the high-contrast UI, go
to Settings then scroll down and make sure
"Use High Contrast Styles" is set to ON.

Test plan:
- Enable high contrast UI in Canvas (see above)
- Go through each issue Nathan entered into
  JIRA and compare with the updated UI to make
  sure it is fixed.
- The webAIM color contrast tester can be found
  here: http://webaim.org/resources/contrastchecker/
