Branding

Logos

If you open core_components.ex you will find some functional components for your logo. You can use them in your templates like so:

<!-- Will adapt to the user's color scheme (light/dark) -->

<.logo variant="light" />
<.logo variant="dark" />
<.logo class="h-20" />

<!-- Display the icon part of your logo  -->

<.logo_icon variant="light" />
<.logo_icon variant="dark" />
<.logo_icon class="h-20" />

For this to work with your own logo, you will need to replace the Petal logos:

• /priv/static/images/logo_dark.svg
• /priv/static/images/logo_light.svg
• /priv/static/images/logo_icon_dark.svg
• /priv/static/images/logo_icon_light.svg
• /priv/static/images/favicon.png
• /priv/static/images/open-graph.png

Using Figma to create your assets quickly

We created a Figma file to easily create and import these assets. Just replace the icon and text with your own brand, and Figma will export all 6 files for you to place straight into your /priv/static/images folder.

There are more detailed instructions inside the Figma file for you.

Colors

Petal Pro and Petal Components expects you to define a primary and secondary color. These typically represent your brand.

In the file /assets/tailwind.config.js you will see the primary and secondary colors defined:

const colors = require("tailwindcss/colors");

module.exports = {
  content: [
    "../lib/*_web/**/*.*ex",
    "./js/**/*.js",
    "../deps/petal_components/**/*.*ex",
  ],
  darkMode: "class",
  theme: {
    extend: {
      colors: {
        primary: colors.blue,
        secondary: colors.pink,
      },
    },
  },
  plugins: [require("@tailwindcss/forms"), require("@tailwindcss/typography")],
};

By default the primary color is blue, and the secondary is pink. You can check out a list of Tailwind color options here. If you want a custom color, you can check out tailwind.ink.
