Start with the documented color character
Santorini Blue is a cool blue with gray undertones. Temperature is a useful description, but neighboring materials can change the impression. Santorini Blue's cool gray undertone offers a subdued blue alternative to a clearer, more saturated scheme.
Why the linen upholstery and medium walnut relationship matters
Medium walnut and plain linen supply enough structure that nautical patterns are optional rather than necessary to explain the wall color.
Santorini Blue has an LRV of 44.67; Benjamin Moore Boothbay Gray HC-165 is 43.26. The difference is 1.41 points, with Santorini Blue returning more light under the reference measurement. Boothbay Gray is a blue-gray with a noticeable midtone presence. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Boothbay Gray as a control
Use a warmer and a cooler object already in the room to assess Santorini Blue, keeping their real proportions visible. The target is a coherent relationship with linen upholstery and medium walnut. Do not assume that every blue behaves alike or that all greens belong on the same side of a temperature label.
Separate a persistent cast from a comparison effect
Let the wood and plain fabric establish the scheme before adding patterned blue accessories.
Keep, compare or change direction
Judge the temperature description against the full linen upholstery and medium walnut arrangement. A warm or cool label is a useful starting category; it cannot guarantee that Santorini Blue agrees with every material assigned the same label. The wood-floor pairing guide covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
