Single Product Website - Duplicate Meta Description

Hi all,

My website sells a single product but in 10 different colorways. Each of the different colorways has a different page/URL.

Just got an SEM Rush trial and it's saying that all 10 of these product pages have duplicate meta descriptions and is being flagged as an issue.

We made the meta descriptions the same because it's obviously the same product. Should we:

1. Leave it as is and disregard this flag (duplicate meta description doesn't have that much of an impact).
2. It's best SEO practice to not have different URLs for colorways and this structure should be changed? If so, what is the best structure?
3. Change the meta description for each product page/colorway and make them unique.

Super new to SEO and this is my first business so any help would be greatly appreciated!
