RAL 190-4 vs Tidewater
RAL 190-4 (RAL Effect) and Tidewater (Sherwin-Williams) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 64 vs 65 — so neither will read significantly brighter or darker than the other. ΔE 3.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 190-4 vs Tidewater in Real Spaces
3 real rooms side by side. RAL 190-4 and Tidewater 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

RAL 190-4 vs Tidewater Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 190-4 on one side and Tidewater 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.
