Although, I love soft, pale, barely there yellow, the canary (egg yolk as I call it) yellow is just too garish. I do like the mint green and I'm finding lots of sites that are showing myriad options in décor for it now. I imagine it's one of those "get it while it's hot" colors but it's a beautiful one to me. I've used the hot pink in much smaller doses for my daughter's room when she was little but I doubt I would use it in large quantities. I also deal with blue best in small doses.

Hi Lachie - I assume you have a built-in wardrobe on the wall where the door is? (where the photos were taken from?). I'd suggest combining some of the elements of the suggestions above, but orientate the bed so that it's facing the door when you walk in, then put your desk under the other window. You can then put the bookshelf on the other side of the desk, which might leave you enough room for a beanbag/comfy chair in the corner for reading? Otherwise, you can put the bookshelf under the floating shelf (not ideal I know). I'd leave the bookshelf upright so that it's taking up less floor space, and get yourself a beside table (preferably one with a drawer and a shelf below for extra storage). A rug would be great for pulling the space together, but you might run into some issues with your desk chair getting caught on it, so you'll need to think about that. But if you do get a rug, I'd try to match it to one of the blues in your bedspread. Maybe also think about getting a new lamp - something in pink to pick that up from the bedspread (and maybe wood instead of metal to bring some texture into the space). As jmm1837 says, some more art on the walls would be good and will help pull the colours together. I see you have a plant there already, what sort is it? Maybe put it in a small wooden or mint green pot and if you get a wide bedside table you could put it on there (which would put it in optimal light under the window). If you want something bigger which is pretty indestructible, you could try a dracaena, next to your desk would make a nice feature. You might want to think about painting the floating shelf too in white? Few other ideas: cushions for your bed; a throw rug; a vignette of glass/vessels for the floating shelf; if you have space (hard to tell) a chest at the end of your bed (as long as that doesn't mean you walk into it coming through the door) for additional storage/seating; and think about a few plants, not just one if you can. In general I'd try to bring some wood elements into the room to make it a bit more homey. Have attached a couple of quick layout possibilities for fun :). Would love to see what you end up doing!

I'd go white with the kitchen. With regards to the splashback, if you want colour and don't want to stick with white, try some colour swatches (I'm thinking beachy greys/dusty light blues) next to the bench when the orange chairs are there to see which harmonise best . I couldn't see a photo of your table. (Only 4 photos showing on my device). Have attached a pic which I googled.

I like the triangular pattern and stag head, however the teal does not seem to blend in well with the dining chair covers. You could try matching the ochre colour in the triangles in the plain cushions.
