Define a reason to reject the sample
Skip Niebla Azul when its color character or depth conflicts with a fixed finish you plan to keep. The main issue to resolve here is blue in both the sunlit wall and the shaded return. Niebla Azul has more reflectance than deep slate blues yet enough body to be a visible light-blue wall.
Why the warm linen and natural wood relationship matters
Natural wood and warm linen provide a reason to inspect both sunlit and shaded views rather than decide from a single cool-looking photo.
Niebla Azul has an LRV of 53; Sherwin-Williams Sleepy Blue SW-6225 is 58. The difference is 5 points, with Sleepy Blue returning more light under the reference measurement.
The material conflict matters more than popularity
Reconsider Niebla Azul when its defining color direction is the part you are trying to suppress. Accessories should develop an accepted palette, not camouflage a wall you dislike. Compare a different hue or level of restraint before buying furnishings solely to make the original sample work.
Choose the next sample for a specific reason
Check that the shaded wall retains an appealing blue before carrying it into an adjoining room. The undertones and neighboring colors covers that related choice. The physical-sample checklist covers that related choice.
If making Niebla Azul work requires replacing materials you intended to keep, revise the paint shortlist first. A successful sample should resolve the room brief, not expand the renovation without a clear reason. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
