Change style of individual features on a layer

Aeseir

I am wondering if it is possible to set style of a individual feature.

Currently I use a custom renderer to determine the style of features on the layer, however, sometimes i want to change a style of a particular feature dynamically (e.g. when i click on it i want to change them to another color).

 

I been looking  at the docos but cannot find the right bit for it.
