Gradient color palettes using the diverging and sequential continuous color
palettes in Tableau. See tableau_color_pal() for discrete color
palettes.
Usage

A palette function. It takes a numeric vector x of values between 0 and 1 and returns a character
vector of hex colors interpolated along the palette, for use as the palette argument of
