I agree, it doesn't work- too dark and busy. I'd go with a travertine tile in a pale cream to match the background color of the countertops. Your cupboards will standout and won't compete visually.

The issue is that glass mosaic is just too busy and dated these days. It's also super dark so it's sucking all the light.

A light cream tile would work best. You said you can't remove the backsplash, not sure if that's because of money or you're physically unable to remove it. If it's money live with it for now and save up. You don't need to splurge on a super expensive backsplash, cheaper tiles work fine.

Are you able to redo it with a cream tile? Perhaps something like this that we used in a project for a client?

Your kitchen looks beautiful! However, I agree that your backsplash tile is too dark and busy with the gorgeous Solarius granite. Unfortunately, the only way around this issue is removing the backsplash tile and replacing it with something else. To my knowledge, you usually cannot tile over top of existing wall tile--that is generally only sometimes possible with floor tile. I suggest living with it for a little while to see how you still feel about it a few months from now. If you still do not like, you will need to remove it and put up a new backsplash tile instead. Best of luck!

If removing is not an option, I would paint it over, with a glossy paint of a light color.

Your kitchen is beautiful! I love the granite you chose! If you are able to remove, I do agree it is a tad dark. I would choose a light tan subway tile to compliment the granite and cabinets! :) Hope everything works out for you!

All of you suggesting the travertine tile, what part of "The backsplash removal is not an option" did you not understand? OP is asking for a way to make it work, not change it out.

And quite frankly, that travertine isn't exactly a step up. I wouldn't do that either.

DIY Freak-It goes perfectly fine w/what you have. darkness/busy look, that's different. The colors work great. try some additional under cabinet lighting to brighten up the darker spots. Keep counter items at a bare minimum. the last thing you want is 'stuff' on the counter for more chaos. keep the countertops bare and non-needed items stored away.

the wine rack adds to busyness. I realize it's there and you need it, but all of the 'detailing' you have w/these cabinets (seeded glass, wine rack, rope trim, molding) is just another list of items competing w/the granite and the backsplash. everyone is fighting to take center stage.

Oh, change out those white outlets/and covers, to black. those white ones stand out like a sore thumb.

Not a travertine fan here. The countertop looks dingy with the backsplash IMO. That said, your second picture is fun - lovely contrasts in the backsplash colors.

Would you be willing to take a few pictures from further back? That would very much help. It's important to factor in the floor and walls and ceiling.

How is your UCL (under cabinet lighting)? Definitely a factor.

Are you willing to swap out the counter top? If not, what are you willing to change?

With black and white tile:

Kudos to you for DIY - your cabinets are very nice! DH and I are very much DIY-ers, which means lots of rework for DH as I figure out what works and doesn't.

I think if you went with a soft white on the walls it would calm things down a bit. and I'm sorry to inform, the fluffy green rug and the other, should really go! lol

The dark outlets and hardware look great! Kudos to DH.

This color seemed to work with the countertop/cabinets and backsplash. red 228 green 195 blue 149.

You didn't ask, but for future reference (next time around!), I'd also suggest that the backsplash end earlier than it does.

Picking the right white is always a struggle - here I am trying to pick up color from the countertop for the walls and the backsplash for the rug:

I don't think the yellows and greens you have on the countertop work with the current paint color. They pop against the backsplash certainly!

You're welcome! I don't have names and suggest you ask the color experts for actual suggestions, closer to this color, if you like. Mix is: Red 231, Green 219 and Blue 200. Then (or also!) take your counter top, backsplash, floor and cabinet samples with you to the paint store and see what colors work with all four.

Get rid of the light counter in favor of plain black. Then add under counter lights. It will be fine.

Right now, the counter and the splash are in a Death Match over the kitchen and the kitchen is the Loser. You need to figure out if you want to turn to the Dark Side? Or the Light Side. Straddling both camps Does Not Work.

Who is going to get thrown off the island? Just like Highlander, There Can Be Only One!

You can’t do magic. One or the other needs to go. No other real solution. It will always look like a DIY design mistake if you keep it as is.
