Painting my Cat tunnel black, whats the best looking way to transition the front

[Pachanga_rick]

Looking to paint the tunnel black and I'm having a hard time find some good pictures of other black cat tunnels and how they transition the front sponson / decks / bottom..

anyone have any pictures or ideas? I could just do a hard line, but I feel there must be a better way.

I think it looks good when it breaks at the bottom inside chine edge and continues to having a black transom. Top edge could split the tunnel at the center of the leading edge and go fwd to where it meets the chime. If you have a rub rail then just go up to that edge.

This is what I'm working with. The transom will be black and the sides and hull will be a BRIGHT color (still picking it)
