Don:
I really don't know if you are joking or not, but, Kubota has 2 different shades and glosses of Orange. Orange I is the original orange. It was used on early models of Kubotas. Orange II is the higher gloss deeper orange that is used on late model tractors. Let's add a little more spice....There is ROPS Grey and chassis blue.
I believe that Kubota went to Orange II as the Orange I was prone to fading and dulling.
