yugutou Thank you for providing the actual Spine project. I have checked it with 4.1.24 and 4.2.23 but still do not know what the problem is with the slot color. Could you please explain exactly what you think is wrong? If it is difficult to explain in words, please provide a minimal reproduction project of the problem. For example, if you can provide us with a project that shows not the entire skeleton, but some parts of it, with no transformation, just animated slot colors, that will help us clarify what we should be looking at.
