Fix contrast ratio for guide syntax hilighting [ci-skip]

lloydk · lloydk · commit 11fc2e1566ef · 2021-07-16T02:41:10.000-06:00
The theme used for syntax hilighting has a number of colors that do not meet the 4.5:1 minimum contrast ratio of the Web Content Accessibility Guidelines (WCAG) 2.1 standard. All colors that were below 4.5:1 on a background of #eeeeee have been adjusted to be at or slightly above 4.5:1 using tweaked versions of the tools in this repository: https://github.com/mpchadwick/pygments-high-contrast-stylesheets/
