Really Teal vs M371
Really Teal (Sherwin-Williams) and M371 (Tikkurila) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 4-point LRV gap — 10 for Really Teal vs 6 for M371 — means Really Teal will open up a space more effectively. A ΔE of 12.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Really Teal vs M371 in Real Spaces

Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Really Teal has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Really Teal vs M371 Simulated Comparison
5 simulated room previews — drag the slider on each to see Really Teal on one side and M371 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.
