I would like to label data entries with multiple fields (that is easy, using the expression editor) in QGIS 2.18. But I fail to alter the styling of the labels, so that say the colour of the label from one data field (e.g., in the first line) was different to the second label value (second line). An older answer had the standard solution (duplicating the layer, Two different colours in label) I am wondering whether QGIS 2.18 or even the up and coming 3.0 will have a solution.
