Possibly add contrast to text and backgrounds

[joshpetit]

Hey, thanks for creating this application, I really think it is fitting an often overlooked need. I was wondering about the contrast of some of the colors since looking at the demo there seem to be light colors on light colors or dark on darker colors. I do not have a lot of experience with the visually impaired but wonder whether this may be difficult for people.

I'm trying to design an application for the visually impaired and tried to follow this video's advice. So that text stands out more.
Thanks again for all the work on this and I hope to see continued development!
