Sets the color used to draw lines and borders around shapes. This color is either specified in terms of the RGB or HSB color depending on the current colorMode () (the default color space is RGB, with each value in the range from 0 to 255). When using hexadecimal notation to specify a color, use " # " or " 0x " before the values (e.g. #CCFFAA, 0xFFCCFFAA ). stroke(random(100, 255), random(90, 255), random(100, 255)); makes for colors more bright (random starts at 100) Then in 10% of the cases - that’s what the if clause does - we choose a color almost red (with only a small amount of randomness) void setup() { size(1000, 1000); background(000); } void draw() { } void mouseDragged { //assigns random float between 0 and 1 which is used for deciding which color to paint float x = random(0, 1); //assigns random stroke value stroke(random(100, 200)); if (x <= .5) { fill(20, 255, 255); ellipse(mouseX, mouseY, mouseX/4, mouseY/4); } if (x > .5) { fill(random(220, 250), random(20, 50), random(220, 250)); ellipse(mouseX, mouseY, mouseX/4, mouseY/4); } } random colors by marjan puladvand A fork of Processingjs Processing Tutorial Mode.

I Am Also x = random(mouseX-70, mouseX+100 13 May 2019 This article covers the trick to generate a random color everytime in a single line of code so that you need not write down whole hexadecimal 10 May 2016 Creating compositions of random lines is easy with processing. strokeWeight( 10); for(int i = 0; i < width; i++) { stroke(random(255), 100); line(i, Processing's random number generator (which operates behind the scenes) int index = int(random(randomCounts.length)); randomCounts[index]++; stroke(0); also use a normal distribution of random numbers to generate a color palet int: color value in hexadecimal notation: alpha: float: opacity of the stroke: gray: float: specifies a value between white and black: v1: float: red or hue value (depending on current color mode) v2: float: green or saturation value (depending on current color mode) v3: float: blue or brightness value (depending on current color mode) random () \ Language (API) \ Processing 3+. Then, you can define the colors and assign it to the stroke. int R = (int)random (0,255); int G = (int)random (0,255); int B = (int)random (0,255); stroke (color (R,G,B)); Hope it helps!

As colours are separated into red green and blue, you can create a new random colour by creating random primary colours: // Java 'Color' class takes 3 floats, from 0 to 1. float r = rand.nextFloat(); float g = rand.nextFloat(); float b = rand.nextFloat(); Then to finally create the colour, pass the primary colours into the constructor:
