Fetching component properties.

Short answer: It’s a 3528 RGB LED with a common cathode. One pad is the shared cathode; the other three are the anodes for Red, Green, and Blue.

What I can confirm from the datasheet:

Polarity: Common Cathode (datasheet explicitly states “Common Cathode”).
Package: PLCC‑4 with pads numbered 1–4. In your symbol these are P1, P2, P3, P4.

The exact mapping of pad numbers (1–4) to R/G/B anodes and the common cathode is shown in the “Package Dimensions/Polarity” figure of the datasheet, but the PDF text extraction is ambiguous here. If you can confirm which corner is Pin 1 on your footprint (dot/notch orientation) or share a screenshot of that figure, I’ll call out precisely which of P1–P4 are R, G, B, and the common cathode.
