Celestial Cloud 2 vs Steel Symphony 3
Both from Dulux's palette. Celestial Cloud 2 reads as blue, while Steel Symphony 3 reads as blue-grey — two distinct hue families, not close cousins. Steel Symphony 3 (LRV 35) reflects noticeably more light than Celestial Cloud 2 (LRV 32), a difference of 3 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. The ΔE 5.4 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.
