Mariner vs Slick Blue
Both are Sherwin-Williams colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 52 vs 46, Slick Blue will read as the brighter of the two — a 6-point gap that matters most in north-facing or low-light rooms. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 6.6, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Mariner vs Slick Blue in Real Spaces
1 real room side by side. Mariner and Slick Blue 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.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Slick Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Mariner vs Slick Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Mariner on one side and Slick Blue 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.
