Using Simulink

Specifying Colors Programmatically

You can use the set_param command at the MATLAB command line or in an M-file program to set parameters that determine the background color of a diagram and the background color and foreground color of diagram elements. The following table summarizes the parameters that control block diagram colors.

Parameter	Determines
ScreenColor	Background color of block diagram
BackgroundColor	Background color of blocks and annotations
ForegroundColor	Foreground color of blocks and annotations

You can set these parameters to any of the following values:

• 'black', 'white', 'red', 'green', 'blue', 'cyan', 'magenta', 'yellow', 'gray', 'lightBlue', 'orange', 'darkGreen'
• '[r,g,b]'

• where r, g, and b are the red, green, and blue components of the color normalized to the range 0.0 to 1.0.

For example, the following command sets the background color of the currently selected system or subsystem to a light green color:

• set_param(gcs, 'ScreenColor', '[0.3, 0.9, 0.5]')
