I have the following code to draw a number of colored lines.
Instead of having straight lines I would like to draw a barber pole containing the five colors in the thin stripes.

Note that I'm not looking for anything 3D, just diagonal stripes.
like so ///////

This would look something like this:

How do I do this?

Here is the solution I came up with using @marmot's answer.

It is absolutely straightforward to achieve something of this sort. Notice, however, that the only thing I am using from your nice MWE are some colors. This is because I do not know what role the barber pole should play.
