We're currently doing a major (DIY) renovation on a cottage that hadn't been touched for decades. Neither of us like white or neutral tones and couldn't live with somewhere all the same colour. We're also maximalists with lots of interesting (imo!) stuff. We bought all new bedding to complement the colours we'd chosen.
So far we've got -
F&B De Nimes (blue) for our bedroom (bed 2) with coral and olive accents/textiles/rug.
F&B Yeabridge Green for bed 3 with turquoise and red accents/textiles plus jute rug.
The main bedroom is used as a TV room and is going to have vintage teal/black Art Nouveau wallpaper on all walls with 1980s red patterned curtains and a colourful antique Persian rug, plus other red accents.
Our family bathroom will probably be a saturated yellow (I'm in the process of collecting wallpaper/paint samples). The star of the show is going to be a crazily patterned, colourful London Basin Co basin which I bought at the start of the project as I couldn't resist it!
It all sounds a bit mad, but we're decorating for us so choose what we love. The rest of the cottage colour palette is a bit more cohesive (lots of Edward Bulmer pink shades - including Pompadour, Nicaragua and Jonquil) with the other colours we've used as accents. For example, in the Nicaragua snug we have a Yeabridge Green fire surround.
When we've had en suites, we've usually decorated them in a colour that tones with the attached bedroom, but not the same, iyswim, so for example a bedroom that was a light olive with F&B Setting Plaster (pink) accents had a bathroom with Setting Plaster walls etc.
