Green Knoll vs RAL 240-5 in Real Spaces
3 real rooms side by side. Green Knoll and RAL 240-5 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 LRV gap is large enough that Green Knoll will make the room feel meaningfully brighter than RAL 240-5 would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Green Knoll reflects noticeably more light off the walls, making the space read more open than RAL 240-5.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Green Knoll reflects noticeably more light off the walls, making the space read more open than RAL 240-5.

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.
