The only person you have to please is YOU! Do what you want. It sounds neutral to me. Should work well. I, myself, am debating what color to paint when I switch rooms. The one thing I can guarantee you is it will NOT be yellow anywhere. I don't find yellow cheery and it blinds me to pretty much anything else becaue I find it so overwhelming.
My point is, all any of us can do is give OUR opinion but you know you best. If yellow makes you happy, use it (just don't invite me over! LOL). If an off white is what works in your mind's eye - go for it.
Congratulations on a fresh space!
