Hi list,
I will help an person that will use some graphics of R in internet.
But this pearson want to specify the colours. This person want me to create
an pallete of colours like that:
Name of color - Code - Colour
White - 0xFFFFFF - color white (like an box with this color)
I know that is possible with R, but i don't know how.
Thanks for the advance.
Atenciosamente,

The ?col2rgb has examples that produce text tables like what you want, but doing it graphically will be hard: there are 150 different colours to show. There's some code in the ?rainbow examples that displays a smaller number of colours.

Hi Maybe there is some neat function for it but apply(data.frame(t(col2rgb(colours()[1:10]))),1,function(x) paste(as.character.hexmode(x),collapse="")) gives you hex values for colours specified. Then you can use colours()[1:10] to get names (or you can invent your own) and you can print real colours in a plot by using filled rectangle.
