If you want the areas to overlap, try using a transparent colour. For
example, "lightblue" is rgb(t(col2rgb("lightblue")), max = 255) →
"#ADD8E6", so try setting the alpha (opacity) channel to something less
than FF, e.g., "#ADD8E688".
You can also use rgb(t(col2rgb("lightblue")), alpha = 128, max = 255)
to generate hexadecimal colour strings for a given colour name and
opacity value.
