Theme - Difference Between Colors

[CFrez]

While using the themes I noticed that some of the color options don't have much difference, if any, between the primary and secondary color. The worst ones are: cyan, light green, and brown. Ones that are not quite as bad are: indigo, light blue, teal, and blue gray. The rest have great contrast!

Then it seems like the themes excessively use the secondary color for most of the text, which is not how it displays in the demo application.

Looking at the theme files it seems like there might be original files that the theme ones are generated off of? I am more than happy to work through and propose a fix for these items, but was curious if I might be able to get the original files which would make it a little easier.

This is a screenshot showing the light green theme, and also how the secondary color is used for the sidebar as well as other text.
