How to change gallery navigation to custom colours

Site URL: http://andrewmorrisphotography.co.uk

Hi there,

I was wondering if it's possible to change the colour of the gallery navigation numbers to a custom colour. Ideally I would like to change it so it matches the header primary navigation on my website.

Any help would be greatly appreciated.

Add to Home > Design > Custom CSS

.number {
    color: red !important;
}
