The floor finish is the reference
Judge Sleepy Blue against your actual wood finish, not a generic wood species label. The starting material direction here is cream bedding and honey wood. Sleepy Blue is described as warm by its manufacturer, a reason to avoid assuming every light blue has the same cool effect.
Cream bedding and honey wood provide the real context for that temperature description, especially under the lamps used at night.
Test the dominant wood color, not one grain line
Use the broad background of the timber to assess Sleepy Blue, rather than matching one grain streak. Wood contributes color as well as texture. Decide whether the paint should contrast with that warmth or repeat it, keeping the dominant fabric in the same view.
Sleepy Blue has an LRV of 58; Sherwin-Williams Niebla Azul SW-9137 is 53. The difference is 5 points, with Sleepy Blue returning more light under the reference measurement.
The condition for keeping Sleepy Blue
Use the cream fabric as the real temperature test instead of inferring an icy effect from the word blue. The undertones and neighboring colors covers that related choice. The trim color comparison covers that related choice.
Keep, compare or change direction
Keep the Sleepy Blue board vertical at the floor edge. A match to one pale grain line can misrepresent the dominant color across the installed floor. Judge the broad timber background from standing height. If the floor will be refinished, repeat the comparison with the approved new stain sample before ordering the wall paint. The coordinating color options covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
