Set up your brand assets to ensure consistency when updating or switching themes.
Go to Brand Center on the Settings menu
Logo: Upload a logo.
PRO TIP: upload a transparent PNG. Recommended image size is 400x400px (Images over 400x400px will be resized to fit your theme) If no logo is provided, you can customize how your site title looks in the theme editor.
Favicon: The optimal size of a favicon is 16x16 pixels, which is the size in which they are most commonly displayed. The preferred file format for a favicon is JPEG or PNG.
Email Logo: upload a PNG file with a transparent background. Whatever size the uploaded image is will be scaled up or down so that either the height or width (whichever is longer) is 500px. If either side is 500px to start with, then the image will stay the same size and no scaling will occur.
Colors: Your theme will contain 5 branding colors;
Fonts: Set a primary and secondary font. The use of these fonts varies per them but this makes it easy to configure themes.
