Shout if you find something, our kitchen is Cashmere Gloss as well, it's all v.nice - Builder painted the house in Skimming/Shimmering Stone equivalent but it's all a bit samey. As DS pointed out, we still look like we've just moved in 2 months later and urgently need something on the walls that give it a bit of life!!
I like the idea of a sage green but not sure it is fresh, or relaxing, enough for me. Also, I know darker colours (navy, etc) are on trend but not sure we are brave enough! Lots of other muted colours could clash with the cashmere? And the trendy blues around at the minute remind me of bedrooms / bathrooms!!
Would it be boring to have Dulux Timeless through most of the downstairs of the house?!
