When two colours/shades have a contrast of 3:1, then their difference is
not just colour, but the difference in brightness/luminosity counts as
another visual factor.

"Note

If content is conveyed through the use of colors that differ not only in
their hue, but that also have a significant difference in lightness,
then this counts as an additional visual distinction, as long as the
difference in relative luminance between the colors leads to a contrast
ratio of 3:1 or greater. For example, a light green and a dark red
differ both by color (hue) and by lightness, so they would pass if the
contrast ratio is at least 3:1. Similarly, if content is distinguished
by inverting an element's foreground and background colors, this would
pass (again, assuming that the foreground and background colors have a
sufficient contrast)."
