Deep Lagoon vs RAL 810-4
Where Deep Lagoon belongs to Cloverdale Paint's range, RAL 810-4 is a RAL Effect color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Deep Lagoon (LRV 17) reflects noticeably more light than RAL 810-4 (LRV 14), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Lagoon vs RAL 810-4 in Real Spaces
4 real rooms side by side. Deep Lagoon and RAL 810-4 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.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. The distinction reads clearly at room scale, making the choice between them concrete.
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. The distinction reads clearly at room scale, making the choice between them concrete.

5 simulated room previews — drag the slider on each to see Deep Lagoon on one side and RAL 810-4 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.
