Oooh, I somewhat answered in your Basement question! For most electronics, I prefer dark grey > specific colour > black > white.
- Nintendo Switch is the black Switch with grey Joy-Cons
- Neon Pink/Neon Green Joy-Cons (currently using; I kind of want the pastel purple/pastel green pair, but that's beside the point!)
- Switch Lite is turquoise
- Laptop is "midnight blue", which from a distance just looks dark grey (and as I mentioned in the other thread, I thought it was grey when I ordered it, but I actually really like the colour it ended up being! )
- My phone is peach-coloured, though I ordered it in black. I don't mind the colour
- PS4 is white
- And then anything else, I'd just prefer it dark grey, or as I ordered at the top!
As for decorations, I haven't decorated any of my devices so far!
