Two functions are available to generate random colors. They are random_color and random_extended_color. This help page briefly describes these functions.
The graphics window need NOT be open to use these functions, and neither function takes any arguments.
Random_Color
Random_Color returns a randomly-generated value from 0 to 15 representing one of the named colors (Black, Blue, Green, Cyan, Red, Magenta, Brown, Light_Gray, Dark_Gray, Light_Blue, Light_Green, Light_Cyan, Light_Red, Light_Magenta, Yellow, White).
Example (in a call symbol)
Display_Text(100,100,"Message",Random_Color)
Random_Extended_Color
Random_Extended_Color returns a randomly-generated extended color value between 0 and 241.
Example (in a call symbol)
Display_Number(100,100,Score,Random_Extended_Color)
