The colors by name.

val string_of_name : name -> string

Gives the string equivalent of the argument.

val rgb_of_name : name -> int * int * int

Converts a color name into three integers representing the Red, Green and Blue channels. Channel values are in between 0 and 255.

val hex_of_rgb : (int * int * int) -> string

Convert a tuple of three integers between 0 and 255 into a hex string

type t =
  1. | Name of name
    (*

    A color by name

    *)
  2. | RGB of int * int * int
    (*

    Red, Green and Blue values. Clipped to 0..255 by most (All?) browsers.

    *)
  3. | RGB_percent of int * int * int
    (*

    RBG channels are specified as a percentage of their maximal value.

    *)
  4. | RGBA of int * int * int * float
    (*

    Same as RGB with additionnal transparency argument. Opacity should be between 0. (completely transparent) and 1. (completely opaque).

    *)
  5. | RGBA_percent of int * int * int * float
    (*

    RGB channels specified as percentage of their maximal value. Alpha channel (opacity) is still a 0. to 1. float.

    *)
  6. | HSL of int * int * int
    (*

    Hue, Saturation and Lightness values. Hue is an angle in degree (in interval 0..360). Saturation is a percentage (0..100) with 0 being colorless. Lightness is also a percentage (0..100) with 0 being black.

    *)
  7. | HSLA of int * int * int * float
    (*

    Same as HSL with an opacity argument between 0. and 1..

    *)

The type of colors, either by name, by Red-Green-Blue constructor or by Hue-Saturation-Lightness constructors.

val rgb : ?a:float -> int -> int -> int -> t

build a color from the values of red, green, and blue channels. optional a argument can be used to specify alpha channel (aka opacity).

val hsl : ?a:float -> int -> int -> int -> t

build a color from the values of hue, saturation, and lightness channels. optional a argument can be used to specify alpha channel (aka opacity).

type js_t = private Js.js_string Js.t

A js_t is a valid string representation of a CSS color

A few conversion functions

val string_of_t : t -> string

Convert to a string representation (for debugging purpose mainly).

val js : t -> js_t

Projection from OCaml to Js. js c is equivalent to Js.string (string_of_t c) but with a js_t return type.

val ml : js_t -> t

Projection from Js to OCaml. The function is the dual of js.

val js_t_of_js_string : Js.js_string Js.t -> js_t

Checks the well-formedness of a string or fails with Invalid_argument
