Hi there,

I picked it up from r.colors' grass manual:

http://colorbrewer2.org/

The code bellow cold be usefull for you explore simbols and colors.

x11(900,500)
par(mfrow=c(1,2))
x<-runif(20)
y<-runif(20)
plot(y~x, type="n")
Number.of.symbols<-20
for (i in 1:Number.of.symbols)
 {
 points(y[i]~x[i], pch=i, cex=1.5)
 text((x[i]+0.02),y[i], i)
 }

colors.list<-colors()
Number.of.colors<-100
colors.list<-colors.list[1:Number.of.colors]
plot(0:1,0:1, type="n")
for (i in colors.list)
 {
 x<-runif(1)
 y<-runif(1)
 text(x,y, i, col=i)
 }

cheers
