Way to animate single color channel？

[thanatos_proto]

Does CSS plugin support separately modifying a color channel like splitting control for xyz?

like gsap.to('.my-element', { duration: 1, '--red': '123' }) ;

There are many ways you could do that...

1. use the gsap.utils.splitColor() utility method to get the current value and then create an rgb() accordingly:

2. Or use a CSS variable:

There are a bunch of other ways too, but I don't want to overwhelm you
