How do I... Assign a forecolor change to the highest value between output of two label boxes

First off, ignore the label content: keep the values as numeric (float, double, integer, ...) variables and compare those instead of the text that a label contains. When new output values arrive, update the variables, and then the Label. At that point you can set the foreground colour of both labels to reflect the "highness" - I'd use a ternary conditional operator[^] rather than a min/max or an if...else
