The ‘filter by colour’ in my left column on category pages is showing colours available for the whole site not just the individual categories.
For instance, ‘pink snakeskin’ should only be shown in the Accessories category, but if you are in the ‘Suspender Belts’ category and click on that colour in the ‘suspender belts’ category no results show.
How do I get the filter to only show colours relevant to whichever category a site visitor is viewing?
