I highly recommend the various tempus color schemes[0], they are designed to be high contrast. Tempus is a collection of themes for Vim, text editors, and terminal emulators that are compliant at the very least with the WCAG AA accessibility standard for colour contrast (which stands for a minimum contrast ratio of 4.50:1—while some items have a 7.00:1 rating, or else WCAG AAA). I use one of the AAA schemes. It's not perfect though, certain color pairs are low contrast (typically the "dark" and "light" variant of the same color).
