Opt 1

What colour walls will be next to the Fridge?

The walls next to the fridge will be white :)

Opt 1. Once the fridge is in you will hardly see the panel.

what colour is the fridge, I lean towards 3

The fridge will be black.

with a black fridge i would enclose it in timber, not too crasy about timber on the return

Make the whole enclosure timber not just one side. They need to match

Not option 2 - either of the others would be ok. Option 2 would look silly with a different colour panel each side of fridge.

Paul has not given the context of the position of the kitchen, the left side of fridge recess is actually a wall. So this will add to the correct suggestion for the panel colour.

Option 1 from me.

What colour will the underside of upper cabinets be?

I decided to use do the 3 designs on a kitchen image I found online, that looks remarkable similar to my kitchen design, as shown in these 3 images. One thing to not is we will have 2 pac (Dulux Vivid White) doors for the base cabinets. But the fridge gable and cabinet doors will most likely be laminate (Polytec Polar White Matt), is a very similar (but not exact) colour to the 2 Pac.

Trouble with option 1, is how will you deal with the different colour of the right hand vertical panel?

Colour of the underside of upper cabinets (carcass) would be white. The doors would be Boston Oak. Yes, the main issue with Option 1 is dealing with the slight white colour mismatch of the vertical panel.

I'm thinking it might be safer to have the vertical panel (fridge gable) and cabinet doors above fridge to be Boston Oak, just for matching purposes.

your first photo will give you the best finish, I would also use oak on the underside of all the wall cabinets plus inside of the fridge panel (both sides )

I query the black fridge as that will stand out like a big dark focal hole .

Have you really scrutinised the Vivid White and the Polar White? I feel they’ll clash. What white are you using for the walls? You don’t want to add a third white. And Vivid White is very stark on walls, not my preference.

I'm using Taubmans Trade Pro White Low Sheen Interior Wall paint for the entire house.

Yes, I understand your point about the clash. So, we've decided to go with the Polytec Boston Oak for the fridge gable and cabinets above the fridge. We will stick with Dulux Vivid White for the base cabinet doors. We had a look at the Dulux range and felt that this one went best with our colour palette.

If having the white bulkhead I like the last render with white fridge unit. If you can colour match bulkhead to the cabinet. Also ensure ceiling is in flat ceiling paint not low sheen
