The variables --lexxy-color-ink-light and --lexxy-color-ink-lighter are both set to the same color value #6c757d. These variables should represent different lightness levels in the dark mode color scheme. Consider adjusting one of these values to maintain the intended color hierarchy, similar to how they differ in the light mode (lines 5-6).

	--lexxy-color-ink-lighter: #6c757d;
