Design issue - bar chart of affected grants colours

[mariongalley]

I love the little bar chart showing the percentage of affected grants, but I don't think this dark red and dark teal are sufficiently contrasty as they're both very dark.

We do have in our design system an "error red" (which looks like the one used) and "success green" (different from the teal) but I think the success green is probably still too dark.
