You can define the colors and radius to match your branding. Simply change the design tokens to match your site’s design language.

index.html
<script>
    window.pactto = window.pactto || {};
    window.pactto.coach = 'username';
    window.pactto.company = 'Coach Name';
    // Add designTokens attribute:
    window.pactto.designTokens = {
        primary: '#D5B666',
        primaryTextColor: '#1A1A1A',
        primaryBackgroundColor: '#F4F2EC',
        textInputPrimaryColor: '#1A1A1A',
        textInputPrimaryBackgroundColor: '#E9E2CB',
        textInputPrimaryBorderColor: 'transparent',
        buttonPrimaryColor: '#232225',
        buttonPrimaryBorderRadius: '0',
        buttonPrimaryBackgroundColor: '#D5B666',
        buttonCancelBorderRadius: '0',
        buttonCancelBackgroundColor: '#B8B8B8',
    };
</script>
