Might sound crazy but a subtle two tone might work not colour blocking but a gradual subtle shade diff a soft off white blue grey teal on top that will not fight against the very bright white window frames and keeping a small room light.. and then getting to a soft blue grey darker teal colour with a soft graded border. And consider painting the unit soft white with an all surface soft white mat or soft sheen paint. Pop up a large piece B&W family photo or a family picked piece of wall art or something wacky like a giant gold fish on a white background framed in a thin bright orange frame and job done...or look up dark snugs/dens with rich bold colours can work well if done correctly .. good luck..

I wouldn't make the base units any lighter than they are as they work tonally. I am possibly alone in thinking it actually looks balanced as it is, but if you are going to change it I would match the base units to the window colour. The pic shows a very similar palette to yours, but maybe replace the dark brown to a charcoal colour. White and pink is very feminine. It needs the slabs of dark to balance it.

Thank you for your comments..I'd love to brighten it with a rug but alas oo many dogs and we live in the country so its always muddy in the winter... im really tempted to go all mushroom..Thanks again

Now I think you have a good point there. Choosing a deeper neutral sounds good. I’m a fan of colour and I have a Dulux minty green in my kitchen, F&B Cromarty in my sitting room, Dulux Egyptian Cotton in the bedroom and aqua in the other bedroom. All these shades are soft though so not garish, apart from a navy feature wall in kitchen. Dulux do some lovely neutral shades like Perfectly Taupe, Chic Shadow and Polished Pebble. Of course colours are affected by the light in the room and those sort of shades can look a bit grim in a dark north facing room. PERFECTLY TAUPE CHIC SHADOW POLISHED PEBBLE
