Thunderhead vs Sea Grove
Where Thunderhead belongs to Cloverdale Paint's range, Sea Grove is a Valspar color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Sea Grove (LRV 15) reflects noticeably more light than Thunderhead (LRV 12), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
