Should icons always be the same color as the accompanying text?

I'm designing a timeline in which certain "event cards" are interactive while others are not. I'm running into a problem where the icons on the non-interactive cards look very dark, and therefore interactive, because I'm coloring them with the same HEX quality as the accompanying text ("PROMPT"), which is itself quite dark to conform to accessibility standards. My first inclination is to just make the icon color lighter (after all, it is a heavier weight than the text), but does that violate any rule that text/icon pairings need to be the same color? Really would appreciate any feedback here, thank you!
