Atomic Red vs RAL 450-6
Atomic Red is a Little Greene color while RAL 450-6 comes from RAL Effect. These are both pink-reds, so the question isn't which hue to choose — it's where within pink-red to land. At LRV 12 vs 8, Atomic Red will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. With a ΔE of 1.3, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Atomic Red vs RAL 450-6 in Real Spaces
2 real rooms side by side. Atomic Red and RAL 450-6 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.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Atomic Red gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Atomic Red gives the walls a little more lift.

Atomic Red vs RAL 450-6 Simulated Comparison
5 simulated room previews — drag the slider on each to see Atomic Red on one side and RAL 450-6 on the other.
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.
