Title: Add white icons for colored buttons

Add white icons for the red and blue buttons. Two things to note:

- No white icons for yellow buttons. That's because the dark ones are better suited
- Redeclares all the background positions rather than just using `background-position-x`. That's because Firefox and Opera don't support individual background position declarations
