Where should I put PassOptionsToPackage when loading xcolor?

Question

I'm trying to draw a graph from a table were I have these data:

DIM AVRG1 MAX1 MIN1 AVRG2 MAX2 MIN2

So I would like to draw 6 lines in my graph:

• 2 means
• 2 for the maximum values
• 2 for the minimum values

Moreover I'd like to "mark" the means with a stronger color, like blue and red, and give the other two a different color wich is less strong, for example cyan or orange.

So I included

\usepackage{tikz}
\usetikzlibrary{graphdrawing}
\usetikzlibrary{graphs}

Letting tikz take care of loading xcolor I passed it the following options:

\PassOptionsToPackage{usenames,dvipsnames}{xcolor}

If I try to load xcolor by itself I get an error while this way works fine.

Then I take the values from the file this way:

\begin{tikzpicture}
    \begin{axis}[width=\linewidth, xmin=0, xmax=8192, ymin=0]
        \addplot [thick, blue] table [mark=none, y=AVRG1, x=DIM]{time1-CPU.data};
        \addplot [small, cyan]table [mark=none, y=MAX1, x=DIM]{time1-CPU.data};
    \end{axis}
\end{tikzpicture}

This does work because cyan is in tikz [2]. But let's suppose that instead of cyan I'd like to use Cerulean which is xcolor [1], then I get the following error:

 Package pgfkeys Error: I do not know the key '/tikz/Cerulean' and I am going to ignore it. Perhaps you misspelled it

How can I make it work? Thank you!

I've left all the packages inside because I don't know if any of them can clash with another (?).

Compiling this gives:

Package xcolor Error: Undefined color `Cerulean'.

And

Package xcolor Error: Undefined color `tikz@color'.

Answer 1

Here is an example that shows Cerulean works just fine:

Code:

\PassOptionsToPackage{usenames,dvipsnames}{xcolor}
\documentclass[border=2pt]{standalone}
\usepackage{pgfplots}

\begin{document}
\noindent
\begin{tikzpicture}
    \begin{axis}
        \addplot [thick, red,      mark=none] {x+3};
        \addplot [thick, Cerulean, mark=none] {-2*x-4};
    \end{axis}
\end{tikzpicture}
\end{document}

You can define your own colours at the start

\definecolor{Blue}{rgb}{0.0,0.0,0.7}
\definecolor{Red}{rgb}{0.7,0.0,0.0}
\definecolor{Green}{rgb}{0.0,0.5,0.0}
\definecolor{Gray}{gray}{0.85}
\definecolor{LightCyan}{rgb}{0.88,1,1}
\definecolor{White}{rgb}{1,1,1}
