I want to separate two labels and then coloring each one separately, using QGIS 3.4.1. So, I was trying to color a label within the Expression Dialog. However, I could not figure out how to wright the function.
I tried all the Color function, but it did not worked. The color's name was taken from the "Select Text Color" within the "layer Styling" bar and it a shade of green that supposed to replace the red.
