Terrapin Green vs RAL 240-3
Where Terrapin Green belongs to Benjamin Moore's range, RAL 240-3 is a RAL Effect color. Terrapin Green reads as beige-green, while RAL 240-3 reads as beige-greige — two distinct hue families, not close cousins. They have nearly identical light reflectance values (25 vs 27), so they'll read as similarly Medium in most lighting conditions. The ΔE 4.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Terrapin Green vs RAL 240-3 in Real Spaces
1 real room side by side. Terrapin Green and RAL 240-3 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. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

Terrapin Green vs RAL 240-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Terrapin Green on one side and RAL 240-3 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.
