Inline footnotes need a space before the ^. Notice how^[this looks in the editor] versus how ^[this looks in the editor].
See → Backlink in inline footnote not being displayed properly in live preview mode - #4 by Craftidore Seems a bug, and it’s been around for a while.
IF there is a space, your internal [[Aristotle 1995]] should show the color you picked in Style Settings. This css should be sufficient for changing the footnote color, but leaving your custom internal link color unchanged, if you still want to. (Tested with the default and Minimal themes, custom internal link color via Style Settings in Minimal.)
.cm-inline-footnote {
color: rgba(var(--color-green-rgb), 0.75);
}
