You can do this with rule-based labeling
Select the layer properties of the layer that you are labeling and select the
Labels tab. At the top, select
Rule-based labeling and add a rule for each label (location, time, people). If you want to display a label for every item in the table, just don't add a filter to the rule.
You will need to play with the placement properties of each label to position the labels such that they aren't right on top of each other. In my example I used an arbitrary distance of 5 just to make sure that the labels weren't on top of each other.
To get the custom coloring, go to the
Text tab when editing the rule, and select the drop down next to the color and select
Expression String Builder that comes up you can put in an expression like the following
if("t/f"='t', color_rgb(0,0,255), color_rgb(255,255,0))
In this example, I have a column that is named "t/f" and contains a string value of 't' or 'f'. If the column value is 't', then the text is colored as blue, and otherwise is colored as yellow.
I did this to a sample layer where I had random values of t or f to colorize the strings. Display string is either red or green, and second display string is blue or yellow.
