Hello,
Im designing a PCB and Im going to use JST SH 4-pin connectors. Im planning to use your STEMMA QT cables.
I would like to follow your coloring.
Red - 3.3VDC Power
Black - Ground
Blue - I2C SDA Data
Yellow - I2C SCL Clock
I cannot find any reference to what numbers the pins have. I have the footprint attached.
Can you please tell me what color is on what pin.
Thank you very much!

The STEMMA QT spec is here:

However, be careful with pin numbering. I think the Adafruit created Eagle PCB parts may not follow JST pin numbering order in all cases - so may be reversed.
Carefully looking at a STEMMA QT cable might help:

And compare that to JST SH spec:
