	// 🎨 color

	/** 🎨
	 * Creates a new `Color` object, which is primarily useful for storing
	 * a color that your sketch will reuse or modify later.
	 * 
	 * With the default RGB color mode, colors have these components:
	 * 
	 * `r`/`red`, `g`/`green`, `b`/`blue`, and `a`/`alpha`.
	 * 
	 * The default color format is integer, so set color components
	 * to values between 0 and 255.
	 * 
	 * In q5 WebGPU, the default color mode is RGB in float format, so
	 * set color components to values between 0 and 1.
	 * 
	 * The [`fill`](https://q5js.org/learn/#fill), [`stroke`](https://q5js.org/learn/#stroke), and [`background`](https://q5js.org/learn/#background) functions
	 * accept the same wide range of color representations as this function.
	 * 
	 * Here are some examples of valid use:
	 * 
	 * - `color(255)` (grayscale)
	 * - `color(255, 200)` (grayscale, alpha)
	 * - `color(255, 0, 0)` (r, g, b)
	 * - `color(255, 0, 0, 10)` (r, g, b, a)
	 * - `color('red')` (colorName)
	 * - `color('#ff0000')` (hexColor)
	 * - `color([255, 0, 0])` (colorComponents)
	 * @param {string | number | Color | number[]} c0 color or first color component
	 * @param {number} [c1] second color component
	 * @param {number} [c2] third color component
	 * @param {number} [c3] fourth color component (alpha)
	 * @returns {Color} a new `Color` object

	/** 🚶 Random Walker
	 * 
	 * A random walker is a fundamental concept in generative art and 
	 * computational simulations of natural phenomena. It represents an
	 * entity that takes steps in random directions, creating emergent
	 * patterns over time.
	 * 
	 * Key implementation details:
	 * 
	 * 1. Position tracking - Store x,y coordinates of the walker
	 * 2. Random movement - Use random() to determine step direction
	 * 3. Visualization - Draw points or shapes at each position
	 * 4. Boundaries - Optionally constrain movement to canvas edges
	 * 
	 * Random walkers can model various natural processes like Brownian motion,
	 * diffusion, and can be extended with biased probabilities to simulate
	 * more complex behaviors.
	 * 
	 * @example
// Basic random walker implementation
class Walker {
  constructor() {
    this.x = width / 2;
    this.y = height / 2;
  }
  
  step() {
    // Random direction with equal probability
    let choice = floor(random(4));
    
    if (choice === 0) this.x++; // right
    else if (choice === 1) this.x--; // left
    else if (choice === 2) this.y++; // down
    else this.y--; // up
    
    // Optional: constrain to canvas
    this.x = constrain(this.x, 0, width);
    this.y = constrain(this.y, 0, height);
  }
  
  display() {
    stroke(0);
    point(this.x, this.y);
  }
}
