Inventory items that are the same except for the colour

SUGGESTED

Hello
I have a couple of hundred inventory items that I want to import to Sage 50 Premium using .csv

Many of the items I am referring to come in multiple colours. Can I import just the "master" item (as I like to call it) and somehow differentiate the different colours within Sage OR do I need to have each colour separately as it's own line in the .csv? Every item has a six digit part number. (eg. 1234XX) The first four digits are all the same for the different items and the last two digits reference a colour.

Thanks
