Blue Harmony vs Mesmerize
Where Blue Harmony belongs to Jotun's range, Mesmerize is a Sherwin-Williams color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Blue Harmony (LRV 17) reflects noticeably more light than Mesmerize (LRV 13), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Blue Harmony runs neutral while Mesmerize is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
