Charcoal Slate vs Faded Indigo

Charcoal SlateBenjamin MoorevsFaded IndigoDuluxΔE 8.0Noticeable difference

Where Charcoal Slate belongs to Benjamin Moore's range, Faded Indigo is a Dulux color. Charcoal Slate reads as grey, while Faded Indigo reads as blue-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (15 vs 17), so they'll read as similarly Dark in most lighting conditions. Charcoal Slate runs blue while Faded Indigo is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Charcoal Slate vs Faded Indigo in Real Spaces

6 real rooms side by side. Charcoal Slate and Faded Indigo 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

Bedroom

The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Faded Indigo brings more warmth to the space, while Charcoal Slate keeps things cooler and crisper.

Dining Room

A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Charcoal Slate reads more restrained here, while Faded Indigo adds a sense of enclosure and warmth.
