It's beginning to look like my preference for non-blinking lights is a neurodivergent thing (unsurprising, that), while my choice of only clear lights may be a more personal thing.
DH and I are polar opposites on Christmas tree preference - I love real trees, he loves artificial. That's due to a severe pine allergy on his part, so we go artificial. I love lanky, elegant Noble firs, he prefers a fat, bushy tree. I adore clear/white lights, while he finds multicolored ones more "merry and bright". I want my lights on or off, no blinking. He enjoys a festival of blinking, chasing, fading lights.
We compromised. A spare, elegant Noble fir-style artificial tree with both clear and multicolored lights controlled on separate circuits - when I'm at home the lights are clear and steady, and when I'm out of the room a click of the remote makes them colorful and blinky.
