Hi Xavier,
The colour schemes are added to the Customizer via the following code, which you’ll find in the parent theme’s /inc/customizer.php file:
$wp_customize->add_control( 'writr_color_scheme', array(
'label' => __( 'Color Scheme', 'writr' ),
'section' => 'writr_theme_options',
'type' => 'select',
'choices' => array(
'default' => __( 'Turquoise', 'writr' ),
'blue' => __( 'Blue', 'writr' ),
'green' => __( 'Green', 'writr' ),
'grey' => __( 'Grey', 'writr' ),
'purple' => __( 'Purple', 'writr' ),
'red' => __( 'Red', 'writr' ),
),
'priority' => 3,
) );
I spoke with the author of the Writr theme and he let me know that adding colour schemes to the above code via a child theme is very advanced work.
You could remove the existing colour scheme options and then call new ones with a separate function. Due to how advanced this is, though, I’m not able to dig into the specific code you need.
A much simpler option for achieving what you’re after is to add custom CSS for your new colour scheme via a child theme’s style.css file or the editor of a custom CSS plugin.
Let me know how you decide to go ahead and if you have any extra questions.
