If you have to color the edge, then it's not on the same plane, and while Christine's model is quite exquisite, it is white. When tabs are on the backside of a parts that does not show, like the backside of a cockpit interior, they work fine, but on the fuselage of anything, or a ships hull, it is just awful and ruins many a otherwise good model.
I hate Pepakura for the tabs and it's polygon approach to modeling. You can't even make a true circle in Pepakura. Cut off the damned tabs, make your own strips, then you won't have to color the edges, you will have natural panel lines!! Geez, if you (in general) just think about it, there is no argument. Strips give the advantage of rigidity, and allow you to put the strip on first, let it dry, then fit the next piece perfectly.
Imagine putting sheet rock your living room walls with tabs, then painting the edging to match. That would take a lot of compound to finish, eh? It would look like something out of "Fiddler's Green". Which are mostly copies of more complicated models, dumbed down.
I know this for fact, but if anyone asks me how, you won't like the P.M. I send you. Just take my word for it. I know the designers who worked for F.G., and did it. I wouldn't want to shame them. :hide:
