Currency Symbol in Pricing Table – Can't change colour

Hi Guys,

I’ve searched on the forums and tried the various quick CSS to change the colour of the currency symbol on that attached private link.
Nothing seems to be working. This is the kind of thing I’ve tried:

.pricing-table li.avia-pricing-row small, .pricing-table li.avia-pricing-row .currency-symbol {
opacity: 1;
color: inherit;
filter: alpha(opacity=100);
text-shadow: none;
}

.pricing-table li.avia-pricing-row .currency-symbol { opacity: 1; color: white; }

Nothing seems to be working, can you please help?

Thanks!
