Question about Human Pose Color Mapping in VACE Preprocessing

[hirotong]

Hi, thank you for the great work on this project.

I recently noticed an issue related to the colors used for human pose visualization.

As shown in the images below:

This is an example pose image from the original DWPose repository:

And this is the result I obtained using the preprocessing script from VACE:
vace_preproccess.py

It seems that the joint colors are not consistent between the two. For example, the hand joint is blue (0, 0, 255) in DWPose but appears red in the VACE output.

The difference appears to come from this line in PoseAnnotator
, which reorders the RGB channels.

I understand that exact color alignment with DWPose may not be critical, but I wanted to confirm whether this is intentional and whether VACE was trained with this channel order. This information would be important to know for fine-tuning the model.

Thanks again for your excellent work!
