Changing all same colours from any website

[wwonderfull]

Is there any option or tool where we can change all the same colores used in the website, from header menu to menu hover and fontawesome icons Imean everywhere from that page where there is that specific same color will get changed, is there any way for it like changing the theme of the website?
I found in the published CSS file of the website suppose exemplary #123456 color code can be traced and replaced using the ctrl+f find option in notepad, but is there any feature or tool where the WYSIWYG Web Builder itself can find the color and replace it with another color?
I can change the color manually from the CSS after published, but would have been nice to see what I am seeing and what I am getting before publishing.
