I want to use purple

I like and use this app very much to keep my grocery list to keep a list of the times that I took my Rxs. Etc. my one complaint that I have is that I want to be able to use purple (my favorite color) on a black background. It would be nice to use dark green and blue and dark burgundy on the black background also but at least purple.
