I fell down a colour swatch rabbit hole

I'm very particular about the light/colour temperature of my bedroom. My room in may parents' new house has a north facing window, so I've spent the day looking at colours that won't annoy me, but will also go with the curtains etc that I already have. 

Sooo many swatches - they've all merged into one by now. Best pack it in for the night, before my brain melts.
