A TaskPaper theme based on Ethan Schoonover's Solarized sixteen color palette (eight monotones, eight accent colors), designed for use with terminal and gui applications.
"On a sunny summer day I love to read a book outside. Not right in the sun; that’s too bright. I’ll hunt for a shady spot under a tree. The shaded paper contrasts with the crisp text nicely. If you were to actually measure the contrast between the two, you’d find it is much lower than black text on a white background (or white on black) on your display device of choice. Black text on white from a computer display is akin to reading a book in direct sunlight and tires the eye. Solarized reduces brightness contrast but, unlike many low contrast colorschemes, retains contrasting hues (based on colorwheel relations) for syntax highlighting readability."
You can edit these by hand. Just replace the TaskPaper names with the solarize colour. Check Ethan's usage and development for details.
If you are feeling adventurous, you can download a Python script for churning these out, which will make it (potentially) easier to edit other aspects.
