My road network is broken up into segments. I want to produce a map that shows where the segments start and finish.
I don't really want to create a point layer that shows the location of the ends of each line, but will if I have to. And I know that I could categorise segments and use a colour ramp or random colours, but I was looking for something that would look a little more classy.
I was wondering if there is a way to use a colour ramp – or gradient fill – for lines in QGIS? What I envisage is every line segment starts with one colour and finishes with another colour. This would also serve to indicate line direction – another one of my requirements.
Any ideas?

In the moment there is no way to colour lines with a gradient style.
First buffer your linestrings. Then you can set a gradient colour for the buffer polygons.

Another Idea
requirement: your lines have an disinct ID
Cut your linestrings in very small substrings (that it looks like a gradient).
"______" linestring with id 1 and 100m
"----------" every single substring must have a distinct id or serial number. Here 1 to 10 (one substring 10m). When all the linestrings have the same direction it would start with 1 und end up with the maximum count of substring.
Problem could be the large amount of classes, if you have very long linestrings.
