In product template form i have a custom field like "mycolor"

In  sale order form when i print the quotation i need get the field value "mycolor"

How i can access to the module product and get the field "mycolor" value from sale order form and print in sale order document.

Or how i can put in the sale order document (quotation) the field value "warranty" (<-- This field there is in product template form)

Or how i can display the product template form field value "warranty" inside saler oder form and then print it in the quotation.

Thank you.
