Woocommerce button edit

Hi,

I’m having trouble with the “add to cart” buttons on woocommerce, currently they are purple which I want but I need the color of the font to change to white.

I have this code at the moment

a.button,
.button.alt,
.button,
input.button,
button.button,
a.comment-reply-link,
#commentform #submit,
#btn-cart a,
#btn-cart a span.btn-cart-inner {
	background:#440472!important;
	color:#FFFFFF!important;
}
a.button:hover,
.button.alt:hover,
.button:hover,
input.button:hover,
button.button:hover,
a.comment-reply-link:hover,
#commentform #submit:hover,
#btn-cart a:hover,
#btn-cart a span.btn-cart-inner:hover {
	background:#440472;
	color:#FFFFFF;
}

I have this in Custom CSS but the color of the text is still coming up black and not white.

I am using felicity as the theme.

Many Thanks,

Matt
