The assembler caught this and came up with a solution, of merely rotating the part 90deg. If one zooms in on the left photo it can be more clearly seen.

Researching the root cause, I made the mistake as the datasheet did not indicate the footprint numbering was from the bottom view, so the pads' numbering is reversed.

This can be further checked if one looks at the die and observes the 3 gold bond wires meeting at the common anode.

The correct view is as follows:

As it looks like we can get away with the rotated part, as in no shorts. The color mapping will have to be changed. The color mapping for this revision can be found as follows.

RGB led mapping

The previous mapping is shown in yellow where the new mapping is in pink. This means that software we will have to swap the red and blue channels when interfacing with this led.
