If your product comes in multiple color variants, use color swatches or a drop down list to display each. If you have a default color option, make sure your product images reflect the selected color. Disable variants that are out of stock.
- Swatches are useful if you want to allow your shoppers to quickly determine if the product is available in a color they like
- If you are worried about the lack of page consistency that might come up as a result of having color swatches of different sizes, then a drop down list is a good option to have.
