Celestial Blue vs Mineral Deposit

Celestial Blue reads as blue-green, while Mineral Deposit reads as grey — two distinct hue families, not close cousins.

Where Celestial Blue leans green, Mineral Deposit reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 4.6 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Celestial Blue vs Mineral Deposit in Real Spaces
2 real rooms side by side. Celestial Blue and Mineral Deposit 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
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. Mineral Deposit brings more warmth to the space, while Celestial Blue keeps things cooler and crisper.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Celestial Blue reads more restrained here, while Mineral Deposit adds a sense of enclosure and warmth.

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.
