Epimethius vs RAL 660-4
Epimethius is a Cloverdale Paint color while RAL 660-4 comes from RAL Effect. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. At LRV 40 vs 31, Epimethius will read as the brighter of the two — a 9-point gap that matters most in north-facing or low-light rooms. At ΔE 4.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Epimethius vs RAL 660-4 in Real Spaces
4 real rooms side by side. Epimethius and RAL 660-4 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Epimethius returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Epimethius will make the room feel meaningfully brighter than RAL 660-4 would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Epimethius will make the room feel meaningfully brighter than RAL 660-4 would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Epimethius will make the room feel meaningfully brighter than RAL 660-4 would.

Epimethius vs RAL 660-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Epimethius on one side and RAL 660-4 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.
