Celestial Blue vs RAL 180-1
Where Celestial Blue belongs to Little Greene's range, RAL 180-1 is a RAL Effect color. Celestial Blue reads as blue-green, while RAL 180-1 reads as blue — two distinct hue families, not close cousins. RAL 180-1 (LRV 49) reflects noticeably more light than Celestial Blue (LRV 44), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Celestial Blue vs RAL 180-1 in Real Spaces
3 real rooms side by side. Celestial Blue and RAL 180-1 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — RAL 180-1 gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. RAL 180-1 reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. RAL 180-1 reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
