Goddy god, please help me pick colours for the downstairs of my house

[DitaVonCheese]

Need to buy paint in the next 36 hours.

Hallway will probably be Dulux Natural Calico with paler woodwork. It has two east-facing windows on the stairs so lots of light but not direct light if that makes sense. Stairs may well end up varnished wood as they have turned out to be quite nice, or off-white colour. Oh, quarry tiles on the floor.

Two rooms I need to make a decision on:

(1) Living room has windows facing east and west, so lovely and light :) We will eventually build an extension to the west so will lose the west window but will make it into a huge open doorway so hopefully won't lose too much light. It is a decent size but not massive. Carpet will probably be oatmealish colour, wood off-white, sofas prob brown. Was thinking duck egg blue colour, maybe just on one long wall (room is slightly L-shaped) but worried feature wall is passe plus possibility of clashing with dining room.

(2) Dining room faces west, again will lose window but gain big hole because of extension. Floor currently quarry tiles but might laminate over at some point. I have some gorgeous turquoise, green, pink and orange glass candlesticks I want to go in there and only one I think I could put on the walls is a pale turquoisey colour but then feel as though I'm painting the whole downstairs clashing blues.

Less urgently (as they don't yet exist!) but might have a bearing on the above are the kitchen and extension/family room thingy. Both will face west over the garden, family room will have French doors and lots of windows.

Family room carpet probably same oatmeal-type thing as living room, will probably put in current sofa and chairs which are covered in a quite stylish (no really) leopard-print patterned fabric which is mainly mid-brown but has loads of other colours woven in if you look very closely so goes with most things. Wondering about biscuit/taupe but maybe too dull?

Kitchen will probably have quarry tile-ish floor, white units, wood worktops and white tiles and I'm rather taken with a peacock blue for the walls but this could change.

Oh and the utility room - again white units and wood top. Will probably end up calico in there unless there is any pressing need not to.

Thanks and sorry it's so long

Anyone before I start panic-buying?

I thought hard. But I dunno .

For me, that would be too much blue -- I like the sound of the duck egg, and your candlesticks sound very cool, but is there not a warmer colour you could use to set them off? I think in a proper dining room (especially one with jewel-like candlesticks), you can go for opulent and cosy. And for me turquoise is a bit chilly. What will you be using it for? Is it your usual everyday eating place?

Heartsease

I never thought I'd find myself thinking these words, let alone typing them, but I'm thinking about a limey green colour for the dining room (the candlesticks are lime-ish). Crown do one which isn't too terrifying/blinding (in a tiny square anyway). Until the extension gets built it will be dining room + playroom; theoretically it will be our everyday eating place (and will be for DD), once DH and I grow out of our terrible habit of eating off our knees in front of the telly

Thanks magichomes I've actually never seen calico in the flesh just seen it mentioned on here (probably by you!) and I want a good off-white so that seems to fit the bill. I'm a bit wary of over-thinking the whole thing and am worried that if I don't do it now then it will never get done, so would rather panic-buy than never buy at all :)

Are feature walls irredeemably naff now?

Have also been looking at Crown lime green (for our kitchen). But like I said, I know nothing . I like the idea.

I think I'll have to get some tester pots for the lime. Yeek. We had Crown erm Bamboo Leaf I think (or Willow something - whichever is in the Kitchen range) in our last kitchen and it was lovely (with pale wood doors).
