Using asset catalogs would be nice but it’s still possible to do with just code. If you can use the semantic colors, with a fallback for when they’re not available, it would help as well I think.

There are no semantic colors for gradients or even highlighted search results as in Jason’s screenshot.

And I am not aware of how we can introduce our own semantic colors without asset catalogs, as the RGB value of a semantic color is not resolved until it is being used (i.e. have a graphics context), but there does not appear to be an NSColor API for this (beyond set, but probably can’t rely on that working 100% of the time, e.g. when other colors are derived from the base color).
