I have a variable that I would like to assign the color red to it simply by using RGB{Float64}(1, 0, 0) but I’d like the absolute value of the variable to determine the opacity of the color. How can one change the color opacity in Julia?

Opacity is represented by the A component of an RGBA value. For an opaque red, you’d use RGBA{Float64}(1, 0, 0, 1).
