Example: Get Transparent Version of Color

example_color_alpha <- adjustcolor(example_color,  # Applying adjustcolor()
                                   alpha.f = 0.3)
example_color_alpha                                # Display hex color code in RStudio console
# [1] "#A020F04D"
show_col(c(example_color,                          # Display original & new colors in RStudio
           example_color_alpha))
