How to add multiple images for each variant

How can I use Metafields to be able to add multiple images for each variant, as opposed to the single image that Shopify allows by default?

For example, if I have a product with four colors, when someone clicks on, for example, blue, I want to only display all of the different angles of the blue product. So, if they select blue, they will be shown the main blue image. Clicking to the right in the image carousel will show them other blue product images, and no other product colors.
