| The colors are only visible in the PS-output, not in DVI. If you have a book-class, than replace the section commands with the ones for book. |
Colored Bullets
Write something like
\textcolor{red}{\(\star\)}
Colored Paragraphs
you can also download this code as a stylefile myColor.sty,
than you need only the command \usepackage{myColor} in latex-preamble.
Remember that you have to store this stylefile in a way that latex finds it!
Color with frameboxing
in latex preamble
\usepackage{color}
defining an own color in latex preamble or anywhere else:
\definecolor{myColor}{rgb}{0.9,0.9,0.9}% rgb color model
multiline text in a parbox with a shade of myColor
\colorbox{myColor}{\parbox{\columnwidth}{ bla bla ... the text ... bla bla }}
the same for a framed parbox with
\fcolorbox{framecolor}{shadecolor}{...
Converting a rgb color to cmyk
K = 1 - max(R,G,B); C = (1 - R - K)/(1-K); M = (1 - G - K)/(1-K); Y = (1 - B - K)/(1-K);If you need for a publication always graysaled images, write into the preamble of your document:
\AtBeginDocument{%
\special{ps:
/setcmykcolor { exch 0.11 mul add
exch 0.59 mul add
exch 0.3 mul add
dup 1 gt { pop 1 } if neg 1 add setgray } def
/setrgbcolor { 0.11 mul
exch 0.59 mul add
exch 0.3 mul add setgray } def
/sethsbcolor { /b exch def /s exch def 6 mul dup cvi dup /i exch def sub /f exch def
/F [[0 1 f sub 1][f 0 1][1 0 1 f sub][1 f 0][1 f sub 1 0][0 1 f][0 1 1]] def
F i get { s mul neg 1 add b mul} forall
0.11 mul
exch 0.59 mul add
exch 0.3 mul add setgray } def
}
}
then all colors are converted into gray. The following two images are the original one
and the grayscaled one with the above command sequence.

This solution for a PDF-output with running pdflatex needs a modified pdftex.def which should
go into TEXMF/tex/latex/pdftexdef/ and the newest xcolor package! Otherwise
it won't work.
