Mystere vs Heart Wood
Where Mystere belongs to Behr's range, Heart Wood is a Dulux color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Heart Wood (LRV 28) reflects noticeably more light than Mystere (LRV 25), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Mystere runs red while Heart Wood is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
