Hi @jonForum
If you're using PixiJS, the PixiPlugin can handle all your coloring needs and more.
var tl = new TimelineMax({ repeat: -1, yoyo: true })
.to(sprite, 1, { pixi: { tint: "#ff0" }})
.to(sprite, 1, { pixi: { tint: 0x2196F3 }})
.to(sprite, 1, { pixi: { tint: "hsl(180, 90%, 60%)" }})
.to(sprite, 1, { pixi: { tint: "rgb(236, 64, 122)" }});
