 - `-a author`: Set the author name.
 - `-b amount`: Make the hue colors blend with the color specified by `-B`. 0.0 (default) means no blending, 1.0 makes them the same exact color. If you'd like to have them be the same hue but with different brightnesses, use a value like 0.999.
-- `-B target`: What color to blend the hues with: `foreground`, `background`, `accent`.
+- `-B target`: What color to blend the hues with: `background` (default), `foreground`, `accent`.
 - `-c contrast`: Desired contrast ratio between the foreground and background colors. Default is 7. 21 guarantees the highest possible contrast (i.e. the foreground will either be white or black).
 - `-e`: Equiluminant mode; uses the same luminance for the hues. This keeps their brightness uniform but can make them harder to tell apart.
 - `--hsl`: Treat the background color as being gamma-encoded HSL (i.e. what most people are used to). Wouldn't recommend it, but if it works for you...
