Primary Color

Colors in Konsta UI are a bit tricky, because for example "Material You" design comes with whole set of different colors.

Konsta UI generate all required colors automatically, based on colors provided in konsta.colors section of tailwind config.

// tailwind.config.js

const konstaConfig = require('konsta/config');

module.exports = konstaConfig({
  konsta: {
    colors: {
      // "primary" is the main app color, if not specified will be default to '#007aff'
      primary: '#007aff'
    }
  },
  /*
   * "Usual" tailwind colors can be used for some custom elements and styling.
   * These colors will not suite for Konsta UI components theming
   */
  theme: {
    extend: {
      colors: {
        'my-red': '#ff0000'
      }
    }
  }
  // rest of your usual Tailwind CSS config here
  ...
});

Based on the given primary color, Konsta UI config will generate the following theme.extend.colors in your config:

// will be added automatically to Tailwind config:

theme: {
  extend: {
    colors: {
      // auto generated colors

Secondary Colors

If you want some secondary colors for Konsta UI components, let's say to make some button red, you need to specify these colors in konsta.colors in tailwind.config.js:

const konstaConfig = require('konsta/config');

module.exports = konstaConfig({
  konsta: {
    colors: {
      // "primary" is the main app color, if not specified will be default to '#007aff'
      primary: '#007aff',
      // custom colors used for Konsta UI components theming
      'brand-red': '#ff0000',
      'brand-green': '#00ff00',
    }
  },
  // rest of your usual Tailwind CSS config here
  ...
});

And to apply these colors, we need to add k-color-[name] class to required component, e.g.:

<Button>Usual Button</Button>
<Button class="k-color-brand-red">Red Button</Button>
<Button class="k-color-brand-green">Green Button</Button>

Such colors will be correctly inherited, so k-color-[name] class can be added to parent elements as well, e.g.:

<Page class="k-color-brand-red">
  <Button>Red Button</Button>
  <Button>Red Button</Button>
  <Button>Red Button</Button>
</Page>
