Little Blue Box vs Rivulet

Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Little Blue Box (LRV 49) reflects noticeably more light than Rivulet (LRV 33), a difference of 16 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 11.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
