"Sink" usually means current into a 'thing' then to 0V so I would have thought it related to common cathode when it came to an RGB LED.

Code:
R ---|>|---.
G ---|>|---{
B ---|>|---{
          _|_ 0V

So its commo cathode?

Planing to use TLC5940, so I can place a order for the RGB, but was not sure which one CC or CA.

Place an order of 20 CA RGB leds.
Soon will start to learn to control.
