Sales Order - Adding Specifics to a product

Hi, I have several products which are sold in different colours. My product title lists as " 10 Colours Available" which can be selected by drop down if purchased online, however when manually taking an order by phone etc and i create a sales order using these products, how can i make note of the colour the customer has selected on there sales order.

The Sales order will only show the product description “10 Colours Available” but not which colour the customer has requested.

Thank you in advance.

That would be much appreciated

I am happy for you to share your knowledge here on this platform, thank you.
