Personally i don't think creating it as a post taxonomy is what is needed  

Thomas, I think the taxonomy way you are going about is the best method.
As you can see, The taxonomy data is not shown to you however, since  
WordPress doesnt handle taxonomies being applied to users.

You can visit /wp-admin/edit-tags.php?taxonomy=color directly and you'll  
be able to manage the Colours there.

You'll need to manually add a dropdown selection to the user edit page  
however based off that taxonomy data, you'd probably have to hook into  
'show_user_profile' & 'edit_user_profile' to add a new Table and table  
row, as well as saving that data manually through the action which fires  
when user data is updated...
