Details
The format of the hex color representation can be either RGB, ARGB, or RGBA.
These hex formats differ only in a way how they encode the transparency value alpha,
ARGB expecting the alpha value before the RGB values (default in spreadsheets),
RGBA expects the alpha value after the RGB values (default in R),
and RGB is not encoding transparency at all.
If the colors some from functions such as adjustcolor that provide color in the
RGBA format, it is necessary to specify the format = "RGBA" when calling the
wb_color() function.
