How to use "random" in processing to choose a color

Expert Solution

Step 1

random function:

random() Generates random numbers. Each time the random() function is called, it returns an unexpected value within the specified range. If only one parameter is passed to the function, it will return a float between zero and the value of the high parameter.
To generate random colors, we randomly mix varying amounts of red, blue, and green together. There are 256 different amount options for each color. That means that when we generate a random color, it could be one of 256^3 = 16,777,216 colors.

Example 1 of using random() in processing:

void setup() {
size(200, 100);
noSmooth();
}

void draw() {
for(int y = 0; y < height; y++){
for(int x = 0; x < width; x++){
float r = random(256);
float g = random(256);
float b = random(256);
stroke(r, g, b);
point(x, y);
}
}
}
This code uses a nested for loop to loop over every pixel in the window. For each pixel, it creates a random color and draws a point with that color at that pixel.
