How can I increase store speed by converting .scss files to .css?

I am facing this issue## SCSS support is deprecated in themes

Convert .scss and .scss.liquid files to .css or .css.liquid for a better performing online store and theme editor.

when i try to convert .scss and .scss.liquid files to .css or .css.liquid through online compiler tools it displays the fata error

Error! parse error: failed at $colorBody: {{ settings.color_body_bg }}; line: 16”

please tell me anyone how can i resolve this issue. The store speed is not icreasing even i have minified the code, optimize the images also optimize tha apps but speed is still 45.Help me how can i resolve it?

{{ settings.color_body_bg }} is liquid code

SCSS compilers will not recognize liquid code

You cannot turny our SCSS file into CSS if there is Liquid in that SCSS file

You can remove the lines of css that contain liquid and place them into inline tag so that you can use liquid and keep liquid variables

Be warned, this can be very time consuming

Another option is to just take the compiled .scss file that Shopify spits out and use that as your CSS file, but that will result in loosing the customizable variables you get with Liquid, everything will be hard coded.
