Co-Branding the Checkout Pages with Your Logo and Colors
The basic checkout experience displays your email address or your business name in the upper
left corner of the checkout pages. You can enhance the checkout experience by setting up
custom page payments in your account profile to specify logos and colors that match the style
of your website. PayPal uses the logo and colors to display the checkout pages. In addition,
you can specify logos and colors with advanced HTML variables that you add to the code of
your button.
