You don't have to refresh them continously, it's enough to update the string of LEDs when you need/want something to change. Just realise that in order to change one of the LEDs in the string you will have to send data for the whole string.

Re: WS2812b and similar LEDs - do we need all time running tight loop for control?

Re: WS2812b and similar LEDs - do we need all time running tight loop for control?
Thanks, I only will have two of such leds, and both should display same color. So what if I connect their inputs in parallel?

Yes, That can be done as I have paralleled up to 8 strings of 30 pixels each.

The WS2812 need fast pulses and your PIC should be fast as well.
The APA101 are much more tolerant and can be driven slower enough for any PIC to handle.
