No one can say without seeing the total room and understanding how you think an accent wall will be successful.

it's the rare room that's improved by an accent wall...

Silverplate will make Crushed Ice look beige.

I think Ellie Gray looks good with Crushed Ice. (Mountain Road is a coordinating color. It has green undertones. It would be a statement.)

Try it. If you don't like it, you might be better off without a accent wall.

If you are trying to decide between the two colors on the lighter wall, I suggest you go with the darker shade. The ither one is too close to the light grey wall.

the accent wall would be the main wall in the living area that extends into the eating area.

Don't paint that wall with an accent color. If it were just the living zone...okay, but extending the color into another specific area (dining) doesn't make for an accent wall.

Suggestion: paint the wall crushed ice and then accent each distinct area with art....

I have already decided on an accent wall, that was not the question lol all these comments not to do it isn’t helping me at all ;)

You did say ALL thoughts are appreciated. You may not appreciate those you didn't want to hear quite as much, but accent walls are somewhat yesterday due in no small part to many being unsuccessful. They very occasionally work if highlighting an architectural feature. Do you have one in that room?

The color looks muddy. I'd look for something else.
