Minimalism animation

Good morning everyone, this post will seem silly to some, since my level of Webflow is very low, I’m starting right now and I want to put an animation but I can’t find the way to do it.
I am trying to copy this animation from this website.


It goes up very subtly and changes the color of the text.

If someone can help me by telling me how I can do it I would appreciate it.

Thank you very much.
