Hoping you can make a suggestion for me: I am updating my master suite at a shore house, and I need to work with some existing conditions. For the bath: it is a small room with a tiny window, so basically no natural light. The photo attached shows the existing shower tile/accent (the light tile), as well as the new floor which has dark grey and some brownish tones (the darker tile). I'll be painting my vanity and walls. Was thinking light grey on walls with med grey on vanity, since floor is dark grey. Any suggestions?

Also-the adjacent MBR currently has a too-bright yellow on walls. Decor/bedding is grey and yellow, which I'm keeping. I either need a pale yellow or light grey for walls. Room is very large with lots of light. Thanks in advance!
