mediapipe Mediapipe Hair Color using Slider error

I was trying to do this, as suggested in your latest comment from this issue thread https://github.com/google/mediapipe/issues/18 ,by setting flip_vertically: true in the graph , I was able to fix the invert issue.

Also about the Color Slider, It does not work but when I set the r/g/b packets to hardcode a single color when calling addConsumablePacketToInputStream(). How to fix this ?

That's a useful answer
Without any help

It works, Thanks.
