Foggy Day vs Sage Slate
Foggy Day (Sherwin-Williams) and Sage Slate (Valspar) come from different manufacturers. Foggy Day reads as blue-grey, while Sage Slate reads as grey — two distinct hue families, not close cousins.

ΔE 7.8 means they're clearly different, but not dramatically so — they'd pair well in the same room.

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.
