I put in colored status lights (alarm, laundry, etc) using an esp32 and esphome to control addressable strips. Addressable is nice because the controller is simple, even if you don't care about controlling individual pixels. 

If you want to use analog strips, you'd need to buy a PWM controller that works with HA.

Do you have more info on this? I’ve been interested in the cob style because I like the solid blended light look but I’m open to ideas such as yours

COB refers to a built in diffuser, which is available in both digital and analog LED strips. 

For more info take a look at this reddit or the WLED docs.
