I went with Muslin & it was the PERFECT option. I can't think you enough for the spot-on suggestion!

I bought this tile , and I just had it placed 2 days and its suppose to be good for high traffic, and I got a mark, and when I try to clean off the mark/scratch turned more black color, the white color of tile rubbing off - do not buy for floor.

Designers ???? I need pictures to see the space . All the elements you state in my head do not work together so I need a visual. BTW I always tell my clients to address lighting before choosing anything so my advics right now is make sure all the lighting is LED I like 4000K to have no yellow cast

I also like what @simplynatural did directly above. ^^ I suspect that, in person, the blues in the wallpaper are a bit more pronounced, even with the scale shown here. Also, the scale shown in these more recent renderings may or may not reflect the true scale of the paper... and even if it does, again, there is the distinct possibility that this limited virtual view does not accurately reflect the actual coloration - as well as the overall effect of the paper, as it appears in person. In any case, I do believe that you still have a myriad of color options that can be used with this paper - even if the small scale and coloration shown here is an accurate depiction of how the paper shows in person. And I think you can still use shades of blue, or green, etc., if you would like to. Here is one general example/view. This room would work with this accent wall if the other 3 walls were painted blue - and this accent wallpaper/treatment has zero blue in it (compared to your paper, which does have some blues in it).
