每个调色板包含若干个前景色、外形线色、背景色。
// Can both use ES6 import and CommonJS require. //import * as chromotome from 'chromotome'; // Palettes can be acquired randomly... let palette = chromotome.get(); // chromotome.getRandom() also works. // ...or by name! palette = chromotome.get('miradors'); // chromotome.getNames() gets you a list of all the different palette names. // A palette consists of an array of colors together with (usually) a stroke color and a background color. console.log(palette.colors); // --> ['#ff6936', '#fddc3f', '#0075ca', '#00bb70'] console.log(palette.stroke); // --> '#ffffff' console.log(palette.background); // --> '#020202'https://kgolid.github.io/chromotome-site/
1.25. 相同颜色
将两个p5.Color颜色对象,转化为#rrggbb格式的RGB字符串,进行对比。相当于以下函数的实现。
参数color1和color2也可以是#rrggbb格式的RGB字符串。
