Latex error: option clash for package xcolor

The original links: https://tex.stackexchange.com/questions/57364/option-clash-for-package-xcolor

So the following is just a copy of the above links:

The xcolor package is loaded by listings. Put the line before \usepackage{listings}.
However your preamble is quite messy. It’s most important that you call hyperref as the last package and put all options to geometry before fancyhdr.
The package ucs is useless with your settings.

Like Harish wrote \PassOptionsToPackage{svgnames}{xcolor} before the line \usepackage{listings} is fine and the problem is the same with TikZ. With \PassOptionsToPackage you can avoid conflicts between options.
