#The idea in what concerns the colors is the following: the reader is free to
#choose his colors (the latex xcolor package is used), but we try to make users
#life reasonably easy. He is allowed to choose tones. The default colors are not
#many, although (from our experience) sufficient for most examples. The reason
#for being few is that we do not want to get confused with the
#colors. Furthermore, when only a few of the available colors are used the
#colors choosen are quite different... 

#########
# Lists of colors (with the same tone)
#all the lists must have length 5. Otherwise, only the first 5 colors are used.
