Terran Empire ships have a different paint job actually
so it's not as easy as one would think....
Here's a few screenies of what mean:

This is a common paint scheme as the other Terran Empire starfleet ships seen or the wreckege thereof have yellow paint schemes on their hulls.
If you need images of other ships that were seen as Terran Empire:

Except of course they had the yellow paint jobs similar to that of the ISS enterprise.
Anyhoo the only reason the ORIGINAl ISS Enterpise (I.E TOS era) was not given the paint job the crew wanted was because they were waaay to cheap back then.
Originally the "ISS" enterprise from TOS was supposed to have a similar "Dagger through Earth" on the foward hull and a darker paint scheme with more flared highlights to make it look different.
