Paints and or stains in Manhattan (Morningside Heights/Harlem)

Good morning. I want to fall in love with my apartment all over again. It's got these beige institutional walls. The ones meant to bring gloom and dreary vibes. Looking for any colored paints you have stored away that you're not using or almost forgot about, that are taking up valuable storage space in your homes(white is ok too). I've found myself to be a mixologist of sorts with colors and want to transfer that skill to the walls of our home. I also refinish wooden furniture so I can definitely use any stains or polyurethanes you have on our furniture as well. Thanks again for your generosity and help.
