Using that example, what you need to do is go one step further

function acf_load_color_field_choices( $field ) {
    // reset choices
    $field['choices'] = array();
    // get the textarea value from options page without any formatting
    $choices = get_field('my_select_values', 'option', false);
    
    // explode the value so that each line is a new array piece
    $choices = explode("\n", $choices)
    
    // remove any unwanted white space
    $choices = array_map('trim', $choices);

    
    // loop through array and add to field 'choices'
    if( is_array($choices) ) {
        
        foreach( $choices as $choice ) {
            
           // split each line on ' : '
           $parts = explode(' : ', $choice);
           // make sure we have 2 parts
           if (count($parts) > 1) {
             $value = $parts[0];
             $label = $parts[1];
           } else {
             // no separator found
             $value = $choice;
             $label = $choice;
           }
           

            $field['choices'][$value] = $label;
            
        }
        
    }
    

    // return the field
    return $field;
    
}

add_filter('acf/load_field/name=color', 'acf_load_color_field_choices');
