Periwinkle vs Dahlia
Periwinkle is a Behr color while Dahlia comes from Sherwin-Williams. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. At LRV 35 vs 32, Periwinkle will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. The tonal difference — Periwinkle's blue character against Dahlia's cool — becomes most visible against white trim or in morning light. At ΔE 7.6, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.

Periwinkle vs Dahlia in Real Spaces
2 real rooms side by side. Periwinkle and Dahlia 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. Periwinkle has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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 — Periwinkle gives the walls a little more lift.

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.
