Lightbox mobile "next" chevron

Hi @tav, is it to possible give the Lightbox linking chevrons on mobil an off white colour ? as they don’t show on the existing white background which is how they are designed. On iMac, the Lightbox background shows beyond the lighboxed content, so white works. But on mobile the chevrons appear over the boded content and have a frustrating tendency to hide themselves!

The navigation arrow colours / positions etc are changeable by clicking on the Navigation Styles button at the bottom:

Okay, thanx
