VS Code with doing a find and pressing alt + enter will highlight/mark all the occurences with an orange dash on the sidebar. Is there a way to modify this color? As seen in the picture of the minimap, we can see the three orange matches of the matches.

Use the following setting:
"editorOverviewRuler.findMatchForeground": "#80CBC4"
The theme color API can be found here. Scroll down to the "Overview ruler" settings in the "Editor colors" section to find other similar settings.
