Thank you all for your input. We have a Menards but they don't have orange. Nobody does. It's not the 1970s anymore I guess. Overtones has some interesting choices. Lighter shades of brown that should work with our boat's color scheme.
We are the proud owners of a garage kept Glastron GT150 in remarkable condition, except for the carpet. Any idea where we might find orange grass carpet with black in it? Best we can do is brown, but we'd prefer to keep it original.
