I tend to think of those as my campaign colours.
Social Democracy and Christian Democracy, reaching out to the wider Left and to the wider tradition of dissent from Whiggery and Jacobinism, capitalism and imperialism, neoliberalism and neoconservatism.
As well as a reminder of how, even as a light-skinned "Mulatto" (to use the preferred term of the man responsible), both of whose parents had been born with Scottish surnames, I was nevertheless deemed racially unfit to be a district council candidate for Tony Blair's unmourned New Labour Party.
Red and black are also the colours on the star-shaped badges of something else. I might even adopt that symbol, but with the colours reversed.
That should be enough to give dear old Oliver Kamm a seizure, considering how he once reacted to something else.
