I believe the fibre you are referring to is coir, coconut husk fibre. Yes, it can handle being constantly wet, for about a year or two. It has been known to just completely fall apart after that point. A much longer-lasting (but less environmentally friendly) option is treefern root panels. If you use lots and lots of silicone, I believe that the coir holds together longer. As for paints, all acrylic paints are non-toxic. And why are you worried about the fumes? You're not going to be painting the foam while the frogs are in there, and once the paint has cured, it doesn't give off fumes anymore. Also, acrylics don't really give off fumes. That's oil paints that do that (and the 'acrylics' used for painting houses, but that's not what you want). Just use any artist's acrylics. Brands: Windsor & Newton, Grumbacher (Galeria), Steven's, Crayola. . . =) If you do use acrylics instead of patio paint, you will want to seal it after it's all dry. Acrylics can turn liquid again with water running over them (they're water-based), and that would be bad! So seal everything with a water-proof sealant, and you won't have to worry. If you can't find one that's non-toxic when cured, try painting a thin layer of Marine Goop (it's a super-strong, non-toxic glue that dries clear) over everything. Do that outside though, because that stuff sure is toxic! You do NOT want to breathe those fumes in! Totally harmless when cured though. Wait. . . why do you want to paint the foam if you're going to cover it with coir? If you're worried that the foam will show through, it probably won't. Just make sure you use black silicone to attach the coir, and everything will be fine. Never use clear silicone. It dries white, and is pretty obvious, especially when wet.

Also confused by the 'foam'. Are you talking about the area below the rounded trim? If so, I can't photoshop anything, but think it would look great if done in a fairly narrow stone veneer. You have a very narrow space to put any stone between the garage doors. As for paint, I'd take a cue from both your beautiful tile roof, which appears to be a clay color, and the stone selection. The stone should complement the roof, and then I'd go a bit darker than the current color but still be something that would coordinate with the roof tile color, and the new stone of course.

I’m a little late to this board, but we used Repose in our old house that we sold. We used It as a whole house color inside and it turned out very pretty. It does reflect a little different in each room bc of windows and lighting. That house was 1600 sq ft, the dining room was very small and it looked great in there, made the room look much larger. All of that said, we just finished painting our current dining room in Repose today. We covered red walls. The first coat I noticed a lot of green undertones, and the color looked much darker. We have the second coat on and it’s pretty, but I’m not feeling like it looks as grey as it did at the other house. Depending on where you stand in the room, it looks grey, greige, or more tannish looking, I don’t know if the mix was off a little or if it’s just the lighting of the room. It is north facing, which is apparently not the best place to put Repose. I’m going to see how it looks in a couple of days and may try another grey.

I like the cab color. The stone has lots of warm tones to it,* so I think you sorta got what you asked for, even if it's not what you imagined. But if you don't like it, you don't like it. Sorry that you are disappointed! My option 4 is "live with it a little while" before making any other moves, if you can. Try to accessorize as others have said. (Spend this time learning more about color theory and undertones, and reviewing the decision process for this color -- "we asked" "that was chosen" ... did you see a sample of this before starting? Is it a shop color or a paint brand color?) Option 2a. Explore if a glaze would be possible that could tone down/neutralize the greens -- note that I have no idea if this would be possible at this stage, let alone less expensive than a whole new paint job, just spitballing. Option 3a. IMO the bright white backsplash is the thing that is really clashing here! *If I recognize that stone right, I had the same one or very similar in a former residence, where it was paired with a very cool-gray marble backsplash and that always bugged me so much!
