This is customizable backlight, so user will be setting the color. Idea with shift register is nice, but if I have to add an extra IC, I can add say 12F683 and use it directly to drive RGB leds. Footprint will be much smaller

You missed the point...
Use same RC circuit to drive APA LED. Apa have Data and Clock pin and you have one pin free.

Out of the box. A small PIC device running the 4 LEDs and reading a 2 bit serial pattern with a longish pause to sync.
