[Dashboard] Change text color based on value.

I am using a dashboard created by myself and I miss one thing. I would like to have a text which will change color based on value.

Example:

I am riding a bike with speed, cadence and HR sensors. So by default my text is white, but, for example, if my speed will be under 25km/h text could change color to orange and if it will be under 20km/h it would be changed to red. Would be great to have the same for HR and cadence (if Cad. is under 85 change text color to orange, if under 80 - red; if Heart rate is over 175 make text red, and so on). Of course colors and values should be set by users.
