Answer 1

Toggle is like on off so at a time you can apply only one color. You cannot apply more.

Answer 2

This JavaScript code do the trick

let i = 0

function addColor (){
let el = document.querySelector (".yellow");
let colors = ["red", "blue", "yellow"]

if (i == colors.length) {
i = 0
for (let color of colors) {
el.style.color = color
}
}
el.style.color = colors[i]
i++
}
