🎨 Show color variants in the advice

You can now show the available color variants of a product in the advice. With that, your customers will immediately know their options

By grouping variants of a product and showing the available colors on the best match, a specific type of product will only appear once in the advice. This also means there's more room to recommend additional alternatives that are actually different and don't just have a different color.

The customer can then simply click on the desired color, which saves an extra click in the purchase process.
