Well John, first of all “Red” in itself was not considered a “color” at the time so it would have to be rose or salmon colored glass?
I personally like it but if it’s missing the “pop or wow” factor that you wanna see then maybe paint the frieze board around the windows the same mustard (not yellow) color as the body.
However if that’s not enough you could always add some engine turn gold leaf in spots then add all the stenciling and just a hint of sky blue like Bills post shows or you could just say screw it, call it done and run it!
That make sense?
Oh and you could paint the trucks an almond color or perhaps rose to match the glass.
