Pewter vs Tranquil Dawn
Where Pewter belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Pewter reads as grey, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. Tranquil Dawn (LRV 55) reflects noticeably more light than Pewter (LRV 34), a difference of 21 points that becomes especially apparent in rooms with limited natural light. Pewter runs blue while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 15.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
