    flame-gradient

    This module generates flame gradients like this one:

    banner

    ...going from dark almost-black red to bright almost-white yellow.

    Usage

    Get one rgb value for a specific decimal value:

    const flameGradient = require('flame-gradient')
     
    const rgb = flameGradient(0.6) // returns 'rgb(255, 150, 1)'
    const rgba = flameGradient(0.6, 0.5) // returns 'rgba('255, 150, 1, 0.5)'

    Generate an entire gradient:

    const generate = require('flame-gradient/generate.js')
     
    const arrayOf1000Rgbs = generate(1000)
    console.log(arrayOf1000Rgbs)
     
    generate(1000, (rgb) => {
      console.log(rgb) // Logs each of 1000 RGB gradient points
    })

    View a gradient with a set number of points in a new browser window:

    # Defaults to 1000 slices 
    npm run view
     
    # Set a number of slices 
    npm run view -- 15

    Accessibility

    These have been tested to have a good balance of vibrant colour and smooth progression in brightness, such that higher values appear brighter to a consistent amount, including in monohrome and across different types of colour vision deficiency (CVD). This is done by incrementing the R, G and B channels in slightly overlapping sine curves, each slightly stretched based on an approximation of that channel's relative luminosity.

    As such they should be usable as colour scales in visualisations.
