Hi, To personnalise your kitchen , it's a good idea to use concrete tiles, they will bring something special into your kitchen.Take a look at Bourkshire.

Ok so depending on floor colours and overall look that she is going for I think (if she is really adamant) that the blue could work if you change the Amaro cabinets to a whiter shade - this will give it an overall crisp, oceanside feel with the warmth of the soft walnut. Otherwise I would contrast it more with a mid-tone colour splashback in grey/brown tones. Again this totally depends of her tastes... Here's a photo that you could show her with the blue splashback - granted it is a little deeper than her selection but at least she can see it on a realistic scale and of course the timber/white cabinets are flipped in this one. Hope some of that helps!

okay!!! A lot of these commenters obviously thought what I did - that the cupboards are a deep browney grey!! I think the responses would have been very different if we knew the cupboards were white. If you re-read thru the responses you will see that. Perhaps try re-posting the dilemma with a better pic. One of those original tiles may actually look ok.

Have you finalised your selections? If you haven’t I’d pause them until you finalise the splashback decision. I can only see the bench top on the screen but it doesn’t look as though it would work with cream - have you seen the two materials together?
