Epimethius vs RAL 670-5
Epimethius is a Cloverdale Paint color while RAL 670-5 comes from RAL Effect. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 40 vs 35, Epimethius will read as the brighter of the two — a 5-point gap that matters most in north-facing or low-light rooms. With a ΔE of 2.2, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Epimethius vs RAL 670-5 in Real Spaces
4 real rooms side by side. Epimethius and RAL 670-5 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
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 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Epimethius gives the walls a little more lift.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The brightness difference is modest but present — Epimethius gives the walls a little more lift.
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 — Epimethius gives the walls a little more lift.

Epimethius vs RAL 670-5 Simulated Comparison
5 simulated room previews — drag the slider on each to see Epimethius on one side and RAL 670-5 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.
