Color highlighting content on the site in browsers: DEFAULT, STANDARD?

Question

css

How to set the default color value without changing the color (since these "settings" are set in the css of WordPress, but I only need to change the color of the selection text)? Is there a color generally standard for all browsers, or do creators use their own colors for each browser? If standard, what is it in the html code?
