Cast Iron vs Eclipse
Both are Sherwin-Williams colors. Cast Iron reads as grey, while Eclipse reads as greige-grey — two distinct hue families, not close cousins. With LRVs of 13 and 14, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Cast Iron's neutral character against Eclipse's warm — becomes most visible against white trim or in morning light. At ΔE 4.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.

5 simulated room previews — drag the slider on each to see Cast Iron on one side and Eclipse 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.
