You didn't read very caref
As Duncan suggested, this will probably get you what you want.
You can set the transparency using alpha.f in adjustcolor().
x <- c(1:5)
color <- c(2,2,3,4,5)
color_transparent <- adjustcolor(color, alpha.f = 0.3)
plot(x, col = color, pch = 20, cex = 4)
plot(x, col = color_transparent, pch = 20,
you will need to specify colours as RGB values and then set transparency
via the "alpha" argument.
e.g.: color=rgb(0,0,0,alpha=0.3)
# will give black (0,0,0) and a transparency of 30%.

here I defined color by numbers, how can I modify
