\description{
The app visualizes colors either along the hue-chroma plane for a given luminance value or along the
luminance-chroma plane for a given hue. Colors can be entered by specifying the hue (H), chroma (C),
and luminance (L) values via sliders, by entering an RGB hex code, or by clicking on a color in the
hue-chroma or luminance-chroma plane. It is also possible to select individual colors and add them
to a palette for comparison and future reference.
}
\details{
\code{choose_color} is a convenience alias for \code{hcl_color_picker} to
go along with \code{\link{choose_palette}}. Another alias is \code{hclcolorpicker}.
