Methods

`Static`parse

parse(color: string): Rgb | null
Parses a color string in hex or rgb(a) format and returns RGB values.
Parameters
- color: string
  Color string in hex (#fff, #ffffff) or rgb/rgba format
Returns Rgb | null
RGB object with r, g, b properties, or null if parsing fails
- Defined in util/color.ts:17

`Static`parseRgba

parseRgba(color: string): Rgba | null
Parses a colour as browsers serialise a computed one: rgb() or rgba(), with commas or spaces, keeping its alpha. A computed colour that stays in another space -- oklch(), lab(), color(srgb ...) -- is not read.
Parameters
- color: string
  The colour, as getComputedStyle gives it
Returns Rgba | null
The colour with its alpha from 0 to 1, or null if parsing fails
- Defined in util/color.ts:54

`Static`invert

invert(rgb: Rgb): Rgb
Inverts an RGB color by subtracting each channel from 255.
Parameters
- rgb: Rgb
  The RGB color to invert
Returns Rgb
The inverted RGB color
- Defined in util/color.ts:68

`Static`getContrastRatio

getContrastRatio(rgb1: Rgb, rgb2: Rgb): number
Calculates the WCAG contrast ratio between two RGB colors.
Parameters
- rgb1: Rgb
  The first RGB color
- rgb2: Rgb
  The second RGB color
Returns number
The contrast ratio between the two colors (1 to 21)
- Defined in util/color.ts:82

`Static`rgbToString

rgbToString(rgb: Rgb): string
Converts an RGB object to a CSS rgb() string format.
Parameters
- rgb: Rgb
  The RGB color to convert
Returns string
CSS rgb() string representation
- Defined in util/color.ts:108

`Static`isEqual

isEqual(color1: string, color2: string): boolean
Parameters
- color1: string
- color2: string
Returns boolean
- Defined in util/color.ts:112
