I am a web designer. 

When I browse web sites I like to change some colors and look at how site will appear when I change the primary color. 

I do this using "inspect elements". But it is very time consuming work since I need to add lot of codes to change everywhere.

Is there any JavaScript code which I can use to change one color code to another color code using browser console.

Basically what I want to is something like below...

**Change #FFF8DC color to #e6dfc6 color everywhere in this site using browser console.**
