I like cool white LEDs specifically because my outdoor lights include a bunch of icicle lights and snowflake shapes and stuff, and cool white reads as “icy” way better than warm white does.
Anyway, if I were Alec, at this point I’d be saying “fuck it” and looking for RGBWW [red, green, blue, warm white] pixel lights that I could program to be the exact hues and brightnesses I wanted. ('Course that’s a whole 'nother rabbit hole, if you want to avoid the expensive-yet-crappy sets with built-in controllers Home Depot etc. sell and get proper ones you can use with your own standalone controller.)
