Looking for feedback on my color choices (coastal grey vs. espresso)

[1985forever]

Spa will be going on a concrete covered patio.  Concrete is not colored.  We have a redwood fence surrounding our yard.  White house, black shutters.  Trying to decide on coastal grey or espresso cabinet (pearl shell on either)

My thoughts on espresso:

Rich looking
Easy to match furniture to
May date itself, due to the rage of "espresso" and "chocolate" colored decor currently (con)
Might show dirt/pollen/dust more? (con)

My thoughts on coastal grey:
 
Not very "warm" looking (con)
May blend into our concrete more smoothly than the contrasting espresso
Might be easier to keep clean looking
Might keep all the colors of the yard/surrounding furniture less complicated looking since it will blend into the concrete better and just be a neutral rather than an accent.

Thanks very much for your input.

 Both look very nice but I lean towards the grey not showing as much.  Specially if you have hard water??   That being said the chestnut is our number one selling color.

Think about standing at your window and looking out at the spa with the cover on it. Whichever color siding you imagine will look best as it sits in your yard as you're looking at it, thats the color to get.
