Немного доработал код:

var button = document.getElementById('submit');

var checkboxes = document.getElementsByName('member');

var radios = document.getElementsByName('color');

var choosencolor = document.getElementsByName('choosencolor')[0];

for (var i = 0; i < radios.length; i++) {
	radios[i].onchange = function(e){
		choosencolor.value = this.parentNode.previousElementSibling.innerHTML;
	}
}

button.onclick = confirm;

function confirm(event){
	event.preventDefault();
	var checkValue;
	for (var j = 0; j < radios.length; j++) {
		if(radios[j].checked){
			checkValue = radios[j].value;
		}
	}
	for (var i = 0; i < checkboxes.length; i++) {
		if(checkboxes[i].checked){
			checkboxes[i].parentNode.parentNode.setAttribute('style', 'background:'+ checkValue + ';');
		}
	}
}
