Sage green. Leaf Green. Cat eye green. Smoky, dusty blues - colours that feel like outdoors, especially with taupe - brown flooring. Then bright colours like red, bright blue, pink & yellow, like flowers amongst the green. And lots of white woodwork to brighten and highlight. I've echoed some colours in furnishings, some have contrasted.
Cool white lighting with additional lights for ambience or task lighting. Add in a small line of LED fairy lights against the darkest blue, like stars in the night sky.
Texture - even when a room is largely in neutral tones to balance the walls, it can be transformed by having a fluffy pile rug, a waffle textured sofa cover, cable knit cushions, smooth linen cushion (in red and white floral pattern), shiny gold satin throw.
Pretty metal - bronze (so green toned) light fittings and slimline shapes.
Plants. So many plants. In attractive pots, in different shapes and forms and sizes. I've got a cheeseplant (£1 to clear looking half dead and consisting of 3 tiny leaves from the crap corner of Waitrose, now 5 foot high), mother in laws tongue five times too big for the tiny pot it's in (yes, I need to divide and repot it), spider plants, yucca, trailing plants, cacti, succulents. Love having flowers as well.
Edwardian elements - tiled bathroom flooring, fully tiled walls for the bath & shower, not too much stuff out. Towels in complementary colour instead of a mishmash of odd ones including a sad greyish one looking like it's been used to clean up the scene of a crime due to hairdye that one's in the airing cupboard. A big, old wooden bed or a brass bedstead. And I'd love to have my old Edwardian wardrobe and chest of drawers, along with a dressing table with a triple mirror and my grandmother's Lalique perfume bottles.
Very small amount of pattern, just the occasional thing with a stylised folk flower print.
Crisp white bedlinen. Love broderie anglaise, as that gives texture without extra colour. Some folk-style embroidered flowers.
Pictures that mean something (largely, a love of old movies, superheroes and music).
Lots of books, CDs, LPs and musical instruments.
I'd like to have white kitchen units with solid wood worktops, a Belfast sink, a range, solid wood kitchen table (no island units), a proper larder, utility room and a ceiling mounted clothes airer, along with a rolltop bath. I've got ancient vintage cooking things as well as modern appliances. Copper and enamelled pots would be lovely.
Most of all, though, space. Not in terms of a large house, but areas of colour without anything demanding attention, so it's relaxing on the eyes instead of shouting at you for attention. Clean, organised, efficient, a mixture of old, new and nature.
