Please note that due to a mixin config issue in Iris the Fabric client needs to be started without the -Dmixin.debug=true flag.
There is still an issue, I could not resolve with the color picker SSBO backend, but the issue already exists in 1.20.1. Firstly, I think on Fabric the loading of the pick_color shader (using ShaderInstanceMixin) does not work, this can be easily fixed using the Fabric API CoreShaderRegistrationCallback. Secondly, the SSBO (tested with the Forge version) always returns white. I tried a few things, but was unsuccessful.
