Dynamically update alpha in color()

I’ve already told you about p5.Color::levels[] for RGBa.

For more undocumented properties, go to:

processing/p5.js/blob/main/src/color/p5.Color.js

/**
 * @module Color
 * @submodule Creating & Reading
 * @for p5
 * @requires core
 * @requires constants
 * @requires color_conversion
 */

import p5 from '../core/main';
import * as constants from '../core/constants';
import color_conversion from './color_conversion';

/**
 * CSS named colors.
 */
const namedColors = {
  aliceblue: '#f0f8ff',
  antiquewhite: '#faebd7',
  aqua: '#00ffff',

You can even find “secret” methods like p5.Color::_getAlpha() there:

github.com

processing/p5.js/blob/0.7.2/src/color/p5.Color.js#L376-L378


      
          p5.Color.prototype._getAlpha = function() {
            return this._array[3] * this.maxes[this.mode][3];
          };
