Description

I have a vector layer with thousands of features, each with a separate numerical id. Colors would help me in recognising what is what visually, so I chose the random colors option: it works perfectly with the old symbology (I'm using that right now).

The new symbology instead will create a color ramp and "stretch" it over the 1000 (or so) features, thus if I have 10 colors the first 100 features will have the same color. As it happens, nearby features will have the same color most of the time, making the color pretty useless. I think the list of the random colors that I choose should be repeated over the sequence of the features, so that following the same example above with 10 colors I will have feature #1, #11, #21 and so on with the same color.

Thanks,
steko

Hello, bug triage...

in QGIS 2.13 (and probably previous versions), you can use the random colors in the categorized renderer to have the same behavior of the (very) old QGIS symbology.

I am closing this bug.
