How to edit task status color

In Sugar 12, I wanted to edit the red/green for Needs Action and Completed to be more saturated instead of lighter and washed out like it is now:

I found a good Styleguide documentation guide for Sugar 12 a couple weeks ago that was really detailed, which I should have bookmarked, as I seem to not be able to find it anymore. I was hoping at least someone would be able to point me to that here. Thank you!
