SCSS Compiler in child theme

I am trying to override scss file from inc/boldgrid-theme-framework-config/scss folder inside my child theme. But its not working.. How can i make changes to this palette-formats.scss file so that it will compile proper css file and will override color-palettes.css file from parent theme.

I am referring code from below link. https://www.boldgrid.com/docs/configuration-file#scss-compiler
Following code i have used in config.php file from my child theme.
$boldgrid_framework_configs[‘customizer-options’][‘colors’][‘settings’][‘scss_directory’][‘default’] = ‘/scss’;
$boldgrid_framework_configs[‘customizer-options’][‘colors’][‘settings’][‘output_css_name’]= ‘/css/output.css’;

Can you please help me so that i can add new color options to my child theme..
