Please consider your aspect and the amount of sun and light your room gets. This makes an enormous difference to the end result of the room, do you want your room to look warm or cool? A lot of reds are going to give the room a warm look, as will the gold drapes but for a cooler look you could bring in white walls. However, you will need to be careful of the shade of red you choose, it could bring out the orange in the flooring as could the gold drapes. If you want something modern and contemporary red/black and white can be a nice fresh colour scheme. The room looks very large so the walls could be painted red for impact or just do the wall behind the bed and the rest of the walls white for a fresh look. Black could also be used as a feature wall behind the bed. A few ideas - [houzz=] [houzz=] [houzz=] [houzz=] [houzz=]

So excited to here about your theme! We are currently extending our house with a similar theme and colour style. We have gone with 'Solver Parchment' in our kitchen (and most of the new section actually), it is not a yellow or cream colour, more of a beige undertone. Lots of warmth and not too strong. Quite similar to half strength Dulux Hog Bristle. (We don't have kitchen cabinets just yet). In the master bedroom we have gone with 'Taubmans Morning Fog ' which is a lovely duck eggy blue colour, very calming. Could also work with your blue accents. Both match with my Laura Ashley wallpaper feature walls very nicely (Laura Ashley Josette in Duck Egg and Sable). Ceiling, cornice, archs and skirts etc all in 'Wattyl Magic White'. Nice and fresh. See pics - please excuse the samples messiness, they have been rolling around in my glove box for a while. Look forward to hearing what you go with and seeing a pic.

Hi - paint colours can be measured. The measurements tell us to which Hue Family each paint belongs. (even black/whites/greys + navies) Also their Value - how dark or light they appear and their Chroma - how near to neutral or colourful they are. The measurements also give us the LRV (light reflectance value) of a colour, showing how much light it will reflect or absorb. This is input into easyRGB.com to find if there are any near matches. 🌈

We are doing white as well, ended up going for Lexicon mid-strength after painting all three, quarter, mid and full in swatches on the wall in our daughters bedroom. Like bargainhunter says the mid throws a blue undertone, turns out my daughter who is 12 now 'hates' it, but it definitely changes in certain lights and it's subtle and I'm still happy we went with it. The warmer whites if they throw anything slightly yellow I don't like them, so I'd rather have a cool blue undertone than yellow, but it depends on what you like. We are actually going to change now to Lexicon quarter for the rest of the house after we paint our 9 year old sons room, and I'm sure we'll get the blue undertone in some rooms, but I'd rather that than yellow. Plus we have timber flooring so it's more likely to make the yellow undertone in a warm white more obvious. We went with vivid white for trims/doors. I honestly think where you live also plays a part. We're in Brisbane, and whilst it's winter and cool at the moment, the majority of the year it's a warm/hot climate so I think cooler colours can assist with that feeling you get of cooling you down or maybe that's wishful thinking lol, but if you are in a colder place I really think that perhaps using that warm white would be a better choice again mentally creating that feeling like you mentioned of warmth and cosiness. I know when I was researching it there were sites that said which warm whites were supposed to be the closest to 'true white' so possibly looking into all of those, each brand will have one, https://www.homestolove.com.au/dulux-white-paint-colours-5396 this article by Three Birds Renovations who seem to love all things white goes through the Dulux white range. Good luck! :)
