Change pricing table column heading background colors

Hi there. In my pricing table I have 3 columns. I want to make the top row, second and third columns different colors. The first column should be transparent. Currently I have the following:

.page-id-25795 .main_color .pricing-table li.avia-heading-row, .main_color .pricing-table li.avia-heading-row .pricing-extra { background-color: color:rgb(242, 159, 46); border-color:#8ed8ed; }

.page-id-25795 .pricing-table > li:nth-of-type(1) {
	height: 45px;
}
.page-id-25795 .pricing-table > li:nth-of-type(2) {
	height: 180px;
}
.page-id-25795 .pricing-table > li:nth-of-type(3) {
	height: 155px;
}
.page-id-25795 .pricing-table > li:nth-of-type(4) {
	height: 135px;
}
.page-id-25795 .pricing-table > li:nth-of-type(5) {
	height: 135px;
}
.page-id-25795 .pricing-table > li:nth-of-type(6) {
	height: 45px;
}

What do I need to adjust to make that happen?
