I'm working with a store landing page that displays the main five product categories. All five category images are displayed inline, and are same height and width. Each has an appropriate label and icon/picture. Essentially, each product category is the same as/equal to the others in importance.
Only three of the product categories qualify for the promotion that will be displayed as a full-width banner/hero at the top of the page, directly above all five product categories. The banner has a link with details as to what qualifies, legal stuff, etc.
Should I call out the three product categories that qualify? Perhaps changing the icon the brand color/white rather than grey/white or in some way highlighting them?
My concern is that the different colors will just be seen as discordant rather than indicative of relevance to the promotion.
