My dad owned a poo-brown Lancia HPE in the 1970s, his friends cruelly suggested that the colour would mask the inevitable ferrous march underneath the paintwork. He had it Ziebarted and eight years later, the bodywork was pristine. But still poo-brown.
My nice new brogues are brown. I like them a lot.
The 2005 Specialized SX trail was bronze/black and looked awesome, as was/did the 2009 Pitch Pro. Brown is okay in flat shades, but I find it challenging when confronted with gloss brown paintwork.
I suppose I’m agreeing that some of the frames in this thread are very, very nicely finished indeed.
