Here’s an example of how to use the method above. All measurements taken are using the device’s own internal light source which is called D65. So straight away you are comparing colours from the same starting point. Using the device, I took measurements of Maggie’s stunning marble work surface. To the naked eye, it appeared a white slab with light grey & dark grey veining. However when measured, the white majority of the slab belonged to the yellow Hue Family & the darkest veins sat in the Yellow-Red Hue Family. Taking further sample measurements of the stone slab flooring, confirmed they too sat in the Yellow Hue Family. So to tie both flooring and work surface together with colour for the island & kitchen units, it made sense to begin looking for colours within the same Hue Family. Getting a Hue Angle reading gives a spot to plot it on the Wheel. The info also gives other key attributes for each colour, making comparison much simpler. Maggie knew she wanted a dark colour for the island, a mid tone for the cupboards & something lighter again for the walls. It’s a new mode of working for most of us home owners, but it’s actually just working with the information companies use to make the colours in the first place. And so it’s a much more objective starting point to finding the right colour for the job. I wish you lots of luck on your quest!

@kazzh Adding a wall as suggested by HU won't allow for the intention of an open plan with the living room as and adding a wall by the current opening will remove a lot of afternoon light from the living room. Adding the laundry to the pantry is certainly possible, it's an idea that has been considered, but we didn't know a) how possible it was to create a new waste pipe and where to run to, possibly the bathroom next door. b) how to position the pantry area to consider a reduced length of waste pipe to avoid a mass of disruption of other units ie cutting holes in them. Moving the patio door isn't impossible, as we can just brick up the current and add a window, then add a patio door to the extension. Thank you so much so far!

One option could be to make the sitting room bigger, than you have drawn, to fit a large sofa and creat a corridor behind the stairs with cloaks cupboard, then the kitchen on the left with island peninsular facing the garden and the extensions forming the dining/seating areas
