im looking for drivers like these for multi color leds

I’d like to drive 2-3 leds in one host individually, one at a time and be able to switch between them. ive been searching and reading this forum for a few weeks and havent found anything better that the one linked above, which seems overly complicated, but modes with memory would be nice. I may be searching for the wrong terms, or maybe what I want doesnt exist yet. even a mod I can make to an existing driver would be great.
