Smalt vs Impulsive Purple
Smalt (Little Greene) and Impulsive Purple (Sherwin-Williams) come from different manufacturers. Smalt reads as blue, while Impulsive Purple reads as purple — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 6 vs 9 — so neither will read significantly brighter or darker than the other. Where Smalt leans blue, Impulsive Purple reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 17.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Smalt vs Impulsive Purple in Real Spaces
2 real rooms side by side. Seeing Smalt and Impulsive Purple in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Smalt vs Impulsive Purple Simulated Comparison
5 simulated room previews — drag the slider on each to see Smalt on one side and Impulsive Purple 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.
