The Attributes used for Search Filters - on the site front-end

Product Attributes, are used for variable products and 
Global Attributes, are used for search and can apply to all products (we also refer to the latter as Standard Attributes)

Notably, the Global or Standard Attributes are predominately used for the Search filters on the product 'Category Pages' and the 'View all Artwork Pages'.

(Category pages have a similar display to the View All Artworks page):

Just select your filter or filters and wait for the available products that match to show. 

In addition to the Global Attribute Filters, there is a purple-coloured bar filter, to filter by price range.
