This is a good color swatch to go off of. Depending on what how dark you want your accent wall, serious gray is also a good color. Personally I like forestwood. That is definitely a dark color. What is the color of your other walls?

My recommendation is to not do a blue/gray accent wall.

The other walls are SW Light French Gray. It has an LRV of 53. Chelsea Gray won't work as it's too close to the Light French Gray. Not enough contrast. Serious Gray is too dark. It's darker than Cadet. It has an LRV of 23. The cadet was 34. I'm considering Dustblu (LRV 32) and Let it Rain (LRV 34).
