Interfaces

interface Color

interface Color {}

A Color object which serves as a base class for colorspace-specific sub-class implementations.

method displayable

displayable: () => boolean;

Returns true if and only if the color is displayable on standard hardware. For example, this returns false for an RGB color if any channel value is less than zero or greater than 255, or if the opacity is not in the range [0, 1].

method formatHex

formatHex: () => string;

Returns a hexadecimal string representing this color in RGB space, such as #f7eaba. If this color is not displayable, a suitable displayable color is returned instead. For example, RGB channel values greater than 255 are clamped to 255.

method formatHex8

formatHex8: () => string;

Returns a hexadecimal string representing this color in RGBA space, such as #f7eaba90. If this color is not displayable, a suitable displayable color is returned instead. For example, RGB channel values greater than 255 are clamped to 255.

method formatHsl

formatHsl: () => string;

Returns a string representing this color according to the CSS Color Module Level 3 specification, such as hsl(257, 50%, 80%) or hsla(257, 50%, 80%, 0.2). If this color is not displayable, a suitable displayable color is returned instead by clamping S and L channel values to the interval [0, 100].

method formatRgb

formatRgb: () => string;

Returns a string representing this color according to the CSS Object Model specification, such as rgb(247, 234, 186) or rgba(247, 234, 186, 0.2). If this color is not displayable, a suitable displayable color is returned instead by clamping RGB channel values to the interval [0, 255].

method hex

hex: () => string;

Deprecated
Use color.formatHex.

method toString

toString: () => string;

Returns a string representing this color according to the CSS Object Model specification, such as rgb(247, 234, 186) or rgba(247, 234, 186, 0.2). If this color is not displayable, a suitable displayable color is returned instead. For example, RGB channel values greater than 255 are clamped to 255.

interface ColorCommonInstance

interface ColorCommonInstance {}

A helper interface of methods common to color objects (including colors defined outside the d3-color standard module, e.g. in d3-hsv). This interface

method brighter

brighter: (k?: number) => this;

Returns a brighter copy of this color. If k is specified, it controls how much brighter the returned color should be. If k is not specified, it defaults to 1. The behavior of this method is dependent on the implementing color space.
Parameter k
A color space dependent number to determine, how much brighter the returned color should be.

method darker

darker: (k?: number) => this;

Returns a darker copy of this color. If k is specified, it controls how much darker the returned color should be. If k is not specified, it defaults to 1. The behavior of this method is dependent on the implementing color space.
Parameter k
A color space dependent number to determine, how much darker the returned color should be.

method displayable

displayable: () => boolean;

Returns true if and only if the color is displayable on standard hardware. For example, this returns false for an RGB color if any channel value is less than zero or greater than 255, or if the opacity is not in the range [0, 1].

method hex

hex: () => string;

Returns a hexadecimal string representing this color. If this color is not displayable, a suitable displayable color is returned instead. For example, RGB channel values greater than 255 are clamped to 255.

method rgb

rgb: () => RGBColor;

Returns the RGB equivalent of this color. For RGB colors, that’s "this".

method toString

toString: () => string;

Returns a string representing this color according to the CSS Object Model specification, such as rgb(247, 234, 186) or rgba(247, 234, 186, 0.2). If this color is not displayable, a suitable displayable color is returned instead. For example, RGB channel values greater than 255 are clamped to 255.
