Update : Can you guys (Prasath & Cornerstone Design Studio India) recommend me laminate color for this setup? I think a grey and white color laminate combo will look good. What you think?

It’s is back painted glass. As a back splash it can be used as it’s easy to clean and maintain. Highly recommended to be toughened. The entire back needs to be cladded in waterproof plywood and then the glass is stuck on to it with special adhesive or silicon gel. Any reservations on using plywood then you can opt for WPC ( wood plastic composite ) which is alternative to play and is totally termite-water proof.

Teal is a very trendy colour, but having it on all four walls may be an overkill in the kitchen, especially with that dramatic chevron dado tile. I hope at least the 4th wall is white! The cabinets have to be white too

Greetings from Dream Design, As per your inputs we suggest some ideas -Don't go with too dark backsplash as it will make the kitchen dull after some time and kitchen will look smaller -You can go with marble/tile or even the same counter top like quartz if you use in counter top you can same also put in backsplash as currently it's in trend -take white color with some black/grey lines marble or quartz -or you can go with white designer lines with grooving Sharing some reference pictures
