Moody Blue Undertones: What to Compare Beside Your Finishes

Moody Blue combines blue with green-gray undertones at a medium depth. A physical comparison is needed to decide how that character works with your own finishes.

Start with the documented color character

Moody Blue combines blue with green-gray undertones at a medium depth. A physical comparison is needed to decide how that character works with your own finishes. Moody Blue has greater depth than Stardew and carries green-gray undertones, making the green side a meaningful part of the blue choice.

Why the cream upholstery and walnut relationship matters

Cream upholstery and walnut can restrain the surrounding palette, leaving the blue-green wall as the room's main color.

Moody Blue has an LRV of 27; Sherwin-Williams Stardew SW-9138 is 43. The difference is 16 points, with Stardew returning more light under the reference measurement. Stardew is a balanced slate blue with a medium reflectance value. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.

Use Stardew as a control

Give Moody Blue enough illuminated area to reveal its color, then move the same board into the normal shadow. Compare it briefly with Stardew. Decide whether the hue is important everywhere or whether a near-black impression is acceptable in the darker parts of the planned surface.

Separate a persistent cast from a comparison effect

Compare it to a less green blue before choosing accessories; let the paint establish the direction. The warm-versus-cool comparison covers that related choice.

Keep, compare or change direction

If the unwanted cast remains beside a permanent finish under normal light, that is a practical reason to replace Moody Blue. If it appears only beside an unused sample, remove the comparison and assess the intended palette alone. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
