LRV 53: the light question for Niebla Azul
An LRV of 53 places Niebla Azul between the pale off-whites and the deeper accents considered here. On a wall, that makes separation from the adjoining finish a useful test. Compare the actual edge rather than predicting contrast from the color name or from a photograph's exposure. The Niebla Azul SW-9137 manufacturer reference supplies the color identity and published specifications.
Niebla Azul has more reflectance than deep slate blues yet enough body to be a visible light-blue wall.
Check the window wall, a shaded return and the room under its usual lamps. Keep warm linen and natural wood together as you move the sample. Record which relationship changes; a different phone exposure is not evidence that the paint will behave differently.
Before ordering boards, organize Niebla Azul and alternatives such as Sleepy Blue with the comparison chips on paintcolorvisualizer.com. Keep the brands and codes attached to the shortlist, then compare physical samples beside warm linen and natural wood.
Blue in both the sunlit wall and the shaded return
Niebla Azul is a light blue with a slate-like quality. The useful starting point for this review is warm linen and natural wood. This is a proposal for assessing the color, not a claim that it has been tested in your home.
Check that the shaded wall retains an appealing blue before carrying it into an adjoining room.
To clarify the difference between Niebla Azul and Sleepy Blue, use Coloraw Color Comparison while keeping the same room and surrounding materials in view. Follow the digital comparison with two labeled physical boards under identical light.
What Niebla Azul SW-9137 actually brings to the palette
Niebla Azul has more reflectance than deep slate blues yet enough body to be a visible light-blue wall.
Use Sherwin-Williams and the complete code SW-9137 when ordering a sample. The working question is blue in both the sunlit wall and the shaded return. A broad family name cannot settle the relationship with warm linen and natural wood.
Use the lighting reference on Paintuma Niebla Azul SW-9137 to plan which appearances to check, then move the Niebla Azul sample through your own daylight and evening conditions. The aim is to evaluate blue in both the sunlit wall and the shaded return, not to treat a rendered scene as a measured result.

Where to test Niebla Azul before repeating it
Start with the room where warm linen and natural wood is most important to the design. On cabinets, place a board under the countertop overhang; in a bedroom, inspect it with the bedside lamps; in a living room, read the wall from the entrance with the main upholstery visible.
An LRV of 53 places Niebla Azul between the pale off-whites and the deeper accents considered here. On a wall, that makes separation from the adjoining finish a useful test. Compare the actual edge rather than predicting contrast from the color name or from a photograph's exposure. If the principal room passes, repeat the check at connecting doorways before adopting one color throughout the house. Different floors and factory whites may require a related palette rather than identical walls.
A palette with Niebla Azul in a defined role
The manufacturer's coordinating suggestions include Mountain Air SW6224, Greek Villa SW7551 and Homburg Gray SW7622. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—warm linen and natural wood—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
Choose the main painted surface before assigning trim and accent colors. In the warm linen and natural wood direction, let the largest fixed surface set the constraint. Compare unequal sample areas that reflect the intended room, rather than assuming three equal paint chips describe the finished balance.
Niebla Azul, Sleepy Blue or Krypton?
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.
Sherwin-Williams Krypton SW-6247 provides another reference at LRV 52. These are separate colors to compare, not promised formula matches. Keep the samples at equal size and orientation, then cover each alternative in turn so the preferred paint is also judged alone.

Check that the shaded wall retains an appealing blue before carrying it into an adjoining room.
Label the board Sherwin-Williams Niebla Azul SW-9137, apply and dry it according to the product directions, and approve it in the intended finish.
