Hi hi!
so to get your text colored in a gradient, I use this site:
BBcode and HTML text effect generator. Create rainbow text effects and more for your blog or forum.

I would usually mess around with the settings and color picker to get what I want, then I scroll down, copy the bb code, then I would go back to KPS, click on the "gear" icon in the text box, paste the code, click the gear again to switch back, and voila, you have your gradient text.
If you are confused about anything, I can dm screenshots since I might not be explaining it well and visuals might help more <3
