Loose RGB

Normalizes RGB color data types to a certain format

Working with different color libraries gets cumbersome when they use different RGB value formats. Now you can normalize the outputs and convert your inputs.

• Normalize any RGB format to {r, g, b, [a]}
• Convert {r, g, b, [a]} to any RGB format
• RGBA support
• Hex support

npm install loose-rgb

import looseRGB from "loose-rgb";

// Convert any type to `{r, g, b, [a]}`
looseRGB.normalize({red: 1, green: 2, blue: 3}) // ? {r: 1, g: 2, b: 3}
looseRGB.normalize("FFBB00AA") // ? {r: 255, g: 187, b: 0, a: 0.66796875}

// Convert `{r, g, b, [a]}` to any type
looseRGB.convert.toCSSValue({r: 255, g: 187, b: 0, a: 0.66796875}) // ? rgba(255, 187, 0, 0.66796875)
looseRGB.convert.toUpperKeys({r: 1, g: 2, b: 3}) // ? {R: 1, G: 2, B: 3}

// Composing the above methods
import {convert, normalize} from "loose-rgb";

const anyToHex = (rgba) => convert.toHex(normalize(rgba));
anyToHex([1, 2, 3, 0.4]) // ? #01020366

looseRGB.normalize(color: RGBUnkown)

Input any color value as color (see convert).

looseRGB.convert[to{ColorType}](color: RGBLowerKeys)

Input an {r, g, b, [a]} color to get a reformatted value. See supported formats for methods.

• .toLowerKeys()
  • {r: 1, g: 2, b: 3}
  • {r: 1, g: 2, b: 3, a: 0.4}
• .toUpperKeys()
  • {R: 1, G: 2, B: 3}
  • {R: 1, G: 2, B: 3, A: 0.4}
• .toFullKeys()
  • {red: 1, green: 2, blue: 3}
  • {red: 1, green: 2, blue: 3, alpha: 0.4}
• .toArray()
  • [1, 2, 3]
  • [1, 2, 3, 0.4]
• .toCSSValue() — Supports with and without spacing between commas, leading zero on decimal
  • "rgb(0, 213, 34)"
  • "rgba(0, 213, 34,.12)"
• .toHex() — Supports with and without pound, case insensitive, with shorthand
  • "#fff"
  • "#000000"
  • "#FFBB00AA"
  • "123"
  • "FFFF"
