Soft Sky vs Rhythmic Blue
Where Soft Sky belongs to Benjamin Moore's range, Rhythmic Blue is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Rhythmic Blue (LRV 69) reflects noticeably more light than Soft Sky (LRV 66), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Soft Sky runs blue while Rhythmic Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
