color
Know that colors are made by combining red, green, and blue in different amounts ( within the range 0-255 ).
Know how to set a Robot's pen color and to set a shape's color in Processing.
Colors are made by combining red, green and blue light (RGB). The amount of each color is determined by a number between 0 and 255 for each of Red, Green, and Blue (RGB).
Processing provides the fill() command to set the current color like this:
If we wanted to set a Robot's pen color to red in a Java program, we could use either of the following:
Processing provides the fill() command to set the current color like this:
fill(255,0,0);The first number reperesents the amount of red, the second green, the third blue. So the above code sets the drawing color to red.
If we wanted to set a Robot's pen color to red in a Java program, we could use either of the following:
rob.setPenColor(Color.RED); rob.setPenColor(new Color(255,0,0));
