Yes you read that correctly, colour with a U. Here in the UK, we spell things a little differently. Anyway, to the guide. Adding a colour picker to the single product template is really easy. When a user picks a colour, the hex value is stored as product meta and once added to the cart, shown under the product name in the mini-cart, cart, checkout, and order editor in the dashboard. If the user has the ability to customise a product with colours, it’s probably best you use a Variable Product type where the user can simply select their colour, then the variation image will reflect this. This solution does not interfere with the product images, it simply allows the user to pick a colour and ties it to the product in the order. This could be useful if specific hex codes are needed instead of thousands of hex codes in a variable drop down list.
