i dont know, but plain red. was one of their colours, they do seem known for their single colour! . do you keep an original colour scheme or be really bold 
against the grain simply because you can ? do you stick to one colour , or have the head tube  diff up to the lugs ? whatever , i reckon it would be a good idea to laquer over the decals. 
its funny how i was thinking that i had not seen any pinarello/s on this forum much and now 3 have come along at once !
