If I have the choice of buying a plain object or an object that is blue, purple or just visually interesting, I’ll usually buy the fun version so long as the price difference isn’t ridiculous. I bought a blue frying pan! My French press is purple. I would legitimately love a tool set that had fun colors as opposed to being just functional.
Other things I like: owls, octopodes, some cats, interesting patterns, the color pink so long as it’s not breast cancer exploitation pink, old-timey diner aesthetics, vintage Fiestaware.
