Installation

npm i --save @rpearce/hex

This library's compilation target is ES2022, but it only uses features from ES2017 and below. If you find you need to support older environments, run this project through your build system.

Usage

import { rgbaToHex } from '@rpearce/hex'

rgbaToHex([]) // '#000000ff'
rgbaToHex([ 120, 55, 168 ]) // '#7837a8ff'
rgbaToHex([ 120, 55, 168, 1 ]) // '#7837a8ff'
rgbaToHex([ 120, 55, 168, 0.5 ]) // '#7837a87f'
rgbaToHex([ 120, 55, 168, 0 ]) // '#7837a800'

blend

Blend together two R, G or B (red, green or blue) color numbers.

interface Blend {
  (x: number, y: number, n?: number): number
}
import { blend } from '@rpearce/hex'

blend(120, 255, 0) // 120
blend(120, 255, 1) // 255
blend(120, 255, 0.7) // 223
blend(120, 0, 0.7) // 66
blend(120, 127, 0.5) // 124

blendAlpha

Blend together two alpha values.

interface BlendAlpha {
  (x: number, y: number, n?: number): number
}
import { blendAlpha } from '@rpearce/hex'

blendAlpha(0.1, 0.9, 0) // 0.1
blendAlpha(0.1, 0.9, 1) // 0.9
blendAlpha(0.1, 1, 0.7) // 0.73
blendAlpha(0.4, 0, 0.7) // 0.12
blendAlpha(0, 0.5, 0.5) // 0.25
blendAlpha(0, 1, 0.5) // 0.5

hexBlend

Blend two hexadecimal color values together, shifting from one color to the next via a fraction between 0 and 1. Hexadecimal equivalent to rgbaCssBlend.

interface HexBlend {
  (hexA: string, hexB: string, n: number): string
}
import { hexBlend } from '@rpearce/hex'

hexBlend('#7837A8', '#FFF', 0) // '#7837a8'
hexBlend('#7837A8', '#FFF', 1) // '#ffffff'
hexBlend('#7837A8', '#FFF', 0.7) // '#dfd7e8'
hexBlend('#7837A8', '#000', 0.7) // '#421e5c'
hexBlend('#7837A8', '#ff6602', 0.5) // '#c75277'
hexBlend('#7837A880', '#FFF', 0.7) // '#dfd7e8d8'

hexToRgba

Convert hexadecimal color codes to an array of RGBa values.

interface HexToRgba {
  (hex: string): [number, number, number, number]
}
import { hexToRgba } from '@rpearce/hex'

// hex-8
hexToRgba('0099ff80') // [ 0, 153, 255, 0.5 ]
hexToRgba('#0099ff80') // [ 0, 153, 255, 0.5 ]

// hex-6
hexToRgba('0099ff') // [ 0, 153, 255, 1 ]
hexToRgba('#0099ff') // [ 0, 153, 255, 1 ]

// hex-4
hexToRgba('09f9') // [ 0, 153, 255, 0.6 ]
hexToRgba('#09f9') // [ 0, 153, 255, 0.6 ]

// hex-3
hexToRgba('09f') // [ 0, 153, 255, 1 ]
hexToRgba('#09f') // [ 0, 153, 255, 1 ]

hexToRgbaCss

Convert hexadecimal color codes to rgba().

interface HexToRgbaCss {
  (hex: string, alpha?: number): string
}
import { hexToRgbaCss } from '@rpearce/hex'

// hex-8
hexToRgbaCss('0099ff80') // 'rgba(0,153,255,0.5)'
hexToRgbaCss('#0099ff80') // 'rgba(0,153,255,0.5)'
hexToRgbaCss('#0099ff80', 0.3) // 'rgba(0,153,255,0.3)'

// hex-6
hexToRgbaCss('0099ff') // 'rgba(0,153,255,1)'
hexToRgbaCss('#0099ff') // 'rgba(0,153,255,1)'
hexToRgbaCss('#0099ff', 0.2) // 'rgba(0,153,255,0.2)'

// hex-4
hexToRgbaCss('09f9') // 'rgba(0,153,255,0.6)'
hexToRgbaCss('#09f9') // 'rgba(0,153,255,0.6)'
hexToRgbaCss('#09f9', 0.12) // 'rgba(0,153,255,0.12)'

// hex-3
hexToRgbaCss('09f') // 'rgba(0,153,255,1)'
hexToRgbaCss('#09f') // 'rgba(0,153,255,1)'

rgbaCssToHex('rgba(120, 55, 168, 0.5)') // '#7837a87f'
rgbaCssToHex('rgba(120, 55, 168, 0.3)') // '#7837a84c'

rgbaToHex

Convert an array of RGBa values to hexadecimal.

interface RgbaToHex {
  (rgba?: [number?, number?, number?, number?] | []): string
}
import { rgbaToHex } from '@rpearce/hex'

rgbaToHex([]) // '#000000ff'
rgbaToHex([ 120, 55, 168 ]) // '#7837a8ff'
rgbaToHex([ 120, 55, 168, 1 ]) // '#7837a8ff'
rgbaToHex([ 120, 55, 168, 0.5 ]) // '#7837a87f'
rgbaToHex([ 120, 55, 168, 0 ]) // '#7837a800'

rgbaToRgbaCss

Convert an array of RGBa values to rgba().

interface RgbaToRgbaCss {
  (rgba?: [number?, number?, number?, number?] | []): string
}
import { rgbaToRgbaCss } from '@rpearce/hex'

rgbaToRgbaCss([]) // 'rgba(0,0,0,1)'
rgbaToRgbaCss([  120, 55, 168  ]) // 'rgba(120,55,168,1)'
rgbaToRgbaCss([  120, 55, 168, 1 ]) // 'rgba(120,55,168,1)'
