Javascript change color button after press it

[Akenekiart]

Hi.

Is it possible to use Javascript code to change the color of the button (button not movie clip object) after pressing it?
this is my code: 

const goodElements = [this.mc1_1, this.mc2_1] //buttons good
const wrongElements = [this.mc1_2, this.mc2_2] //buttons wrong

const Comparison = [...goodElements, ...wrongElements]

goodElements.forEach((element, index) => {
	element.addEventListener('click', () =>{
		points++

		//element.gotoAndStop(1);
		element.mouseEnabled=false;
		exportRoot.stworek.gotoAndPlay("good1");
		exportRoot.goodAnswer.play();
		nextFrame();
	});
})

 Thank you!

element.shape.graphics._fill.style = "#ff0000"; // red
