Some of the colours are hard to see when editing markdown.

from @momack2:

Please change purple color to something readable against the navy background (maybe lilac or pink?). You can use online accessibility tools (example) to ensure the the color contrast between the background and the font is readable.

I personally enjoy using http://colorbrewer2.org/#type=diverging&scheme=BrBG&n=3 in the "diverging" mode to generate color schemes, though that's probably my weird GIS background 🙂

(they are accessible-leaning by default and explicitly colorblind-safe with that option checked)
