mean_col() computes an average color.
Value
A color string of 9 characters: "#" followed by the
red, blue, green, and alpha values in hexadecimal.
Details
We currently compute an average color by using the quadratic mean of the colors' RGBA values.
Examples
mean_col("black", "white")
#> [1] "#B4B4B4FF"
mean_col(c("black", "white"))
#> [1] "#B4B4B4FF"
mean_col("red", "blue")
#> [1] "#B400B4FF"
