How can you change the color of a block based on the input value?

I am trying to get the 'Display' block color in Simulink. Based on the input value, if it is within a certain range, I want the color to change to indicate the change to the user beyond just the number reading. How can I do so? Thanks!

The first thing I could think of was creating a MATLAB Function block that checks the signal incoming to the block. In this block, you can use the following command to change your block colors:

set_param('modelName/blockName','BackgroundColor','red');

I've attached a screenshot:

What kind of issues? Do you have an error message, or does the block color simply not change?
