package color-brewery
Colors palettes and functions to brew colors.
type rgba = Gg.colorA RGBA color.
type cmyk = Gg.v4A CMYK color.
val to_int : rgba -> intto_int c converts the color to 0xRRGGBB where RR, GG and BB are the red, green and blue values expressed on 2 hexadecimal digits. The alpha value is ignored. This is convenient to interact, say, with the Graphics module.
val of_int_exn : ?a:float -> int -> rgbaof_int_exn i returns the color provided as 0xRRGGBB.
val of_int : ?a:float -> int -> rgba optionof_int is the similar to of_int_exn except that it returns None instead of raising an exception.
val to_string : rgba -> stringto_string c converts the color to a string of the form #RRGGBB.
“Continuous” color ranges
val hue : float -> rgbahue h return the color corresponding to the hue h ∈ [0., 360.).
val hue_pct : float -> rgbahue h return the color corresponding to the hue h ∈ [0., 1.).
module Gradient : sig ... endval range : ?grad:Gradient.t -> n:int -> float -> float -> (float * rgba) listrange ~n a b generates a uniform sampling of n points between a and b (with the bounds a and b included in the list of points) together with colors (based on hue at the moment).
val with_colors : ?grad:Gradient.t -> 'a list -> ('a * rgba) listwith_colors l add a color range to the list l.
Color palettes
module Palette : sig ... endFind a color map according to certain characteristics.
