Four independent scores (read the one that fits your goal): Readability 0/100 (fail) · Harmony 55/100 (analogous (soft)) · Distinguishable 16/100 (hard to tell apart) · Match 91/100 (near match). There is no single “good/bad” — a pair can clash for text yet be great for an outfit.
Light Gray and Fog are very close (ΔE 4). They have distinctly different hues (55° apart) and their lightness is similar, so they read as two same-weight colours.
