Mountain Air and Sea Salt: the documented difference
Mountain Air has an LRV of 73; Sherwin-Williams Sea Salt SW-6204 is 63. The difference is 10 points, with Mountain Air returning more light under the reference measurement. Choose by the material relationship as well as the number. Mountain Air is a light green-blue pastel, so its airy description should not be mistaken for a warm neutral specification. Sea Salt is a muted cool green with blue in its published undertone description.

The choice beside honey wood and white cotton
Honey wood introduces warmth, but the sample on the shaded wall still needs to deliver a cool-color impression the room can support.
Set up both candidates with honey wood and white cotton. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Misty has an LRV of 64.
Check the shaded wall with the wood visible; an airy name cannot guarantee a warm-looking room. Assess Mountain Air and Sea Salt alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
