Bracken Slate vs Thunder Clouds
Where Bracken Slate belongs to Benjamin Moore's range, Thunder Clouds is a Dulux color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Thunder Clouds (LRV 17) reflects noticeably more light than Bracken Slate (LRV 14), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Bracken Slate runs blue while Thunder Clouds is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
