You can use blending modes https://css-tricks.com/basics-css-blend-modes/ , or you can use css filters https://www.w3schools.com/cssref/css3_pr_filter.asp , as far as I know this is, maybe not the only way, but the easiest way to do what you want to achieve. There may be some other ways that I am not aware about.
