we are using the Portfolio, Dark version, brick list, hiding nav. When we use the filter on the startscreen (brick list) and just a few thumbnails are shown, there´s a white background appearing under the last row of thumbnails. We wanted to change this colour in the standard grey. This is possible, but it also changes all white backgrounds (portfolio item sites, static sites, etc.). We just want to change only the colour for the portfolio grid as seen on the startscreen. What is to do?
