beer-color

Simple library to convert between beer/malt color units and to hex.

• Convert between SRM, EBC and Lovibond
• Hex conversion is only a rough approximation and not an accurate prediction of actual beer color as this is influenced by a wide range of factors such as lighting, glass size, yeast action, additions, etc.

Usage

Install the module with:

 npm install beer-color

import { ebcToHex, lovibondToHex, srmToHex } from 'beer-color';

const hex = srmToHex(3.6);
// '#efec2e'
const hex = ebcToHex(23.6);
// '#c07238'
const hex = lovibondToHex(0.5);
// '#fafad2'

import { convertColorUnits } from 'beer-color';

const ebc = convertColorUnits(12, 'srm', 'ebc');
// 23.64
const srm = convertColorUnits(12, 'ebc', 'srm');
// 6.096
const lovibond = convertColorUnits(12, 'ebc', 'lovibond');
// 5.06

Documentation

srmToHex(value)

• value number SRM value to convert

returns approximate hex color equivalent

ebcToHex(value)

• value number EBC value to convert

returns approximate hex color equivalent

lovibondToHex(value)

• value number lovibond value to convert

returns approximate hex color equivalent

convertColorUnits(value, sourceUnit, targetUnit)

• value number value to convert
• sourceUnit 'srm' | 'ebc' | 'lovibond' unit of value parameter
• targetUnit 'srm' | 'ebc' | 'lovibond' unit to convert to

returns converted value for the specified unit
