Do you know how I can change a color of a surface in VineCopula::plot.BiCop function? I've tried to use a col argument but it's worked just for color of lines of a grid.

library(VineCopula)
par.gauss<-BiCopTau2Par(1, .7, check.taus = TRUE)
obj.gauss <- BiCop(family = 1, par = par.gauss)
plot(obj.gauss,zlim=c(0,12))

I've tried:

plot(obj.gauss,zlim=c(0,12), col="green")

but it's changed just a color of lines.

You could use

n <- 70
plot(obj.gauss, zlim=c(0,12), col.regions=rainbow(n))

n gives the number of colors used in your plot. rainbow is a color palette, there are several others. Look at ?rainbow, you could use

hcl.colors(n)
rainbow(n)
heat.colors(n)
terrain.colors(n)
topo.colors(n)
cm.colors(n)

and there are several parameters, so for example

plot(obj.gauss, zlim=c(0,12), col.regions=rainbow(120, s=0.5, alpha=0.75))
