I could probably talk about paint colours all day. A lot of hosts would probably say stick to neutrals in an Airbnb, or even just white, but I don't agree. Then again, I host in my own home, so I pretty much decorate for myself, but the guests seem to really like it.
At the moment, most of my house is painted in pale colours, like very light blue or very light grey but there are pops of colour in wallpaper on feature walls and in the furnishings. The bathroom is currently a darker grey, but the only room I've gone for a bold colour is this guest room:
In this photo it actually looks quite similar to the colour @Quincy mentioned, but it's hard to tell on screen. I think the blue changes a lot depending on the light. This colour is Little Greene Airforce Blue.
I definitely want to use more colour/deeper colours in the house and have a very plans, but I keep changing my mind.
The grey bathroom is due for a refresh and I was planning on going for the pale coffee colour I've used in one of the other bedrooms, but now I am thinking pink! I really like the idea of a pale, subtle (not too sugary) pink in there which I think will make it feel warmer and help the new tiles, which are a Zelige style, to stand out. I am thinking something along these lines, and also of painting the window frames black to tie in with the black chandelier:
