Hi @jan_zaczynski 

I think you can achieve this by edit you theme style in CSS file. Here is the link of Magento Guide will help you in customize your style file.

Hello @jan_zaczynski 

you will require to edit the css file of luma theme and change the color based on your need.

Location of the file is - vendor/magento/theme-frontend-luma/Magento_Theme/web/css/source/_module.less

Don't edit directly in the core files - you will require to create a child theme/custom theme for your requirement in the app/design/VendorName/ThemeName directory

Then create your own css file - keeping parent theme as luma and now you will require to change the color of the add-to-cart button.

it is coming from the below class so i have changed it to black :

action tocart primary

.action.primary{
background:#000000;
}

You can refer this article to know about how to create a custom theme - https://www.magestore.com/magento-2-tutorial/3171-2/
