https://stackoverflow.com/questions/5623838/rgb-to-hex-and-hex-to-rgb

Write a nodejs command line program that takes a hex color as an argument and returns the rbg CSS value.

$ node index.js hex \#ffffff

Will print out:

rgb( 255, 255, 255 )

Getting started

Create an index.js file. Run it with node index.js.

Further

Create the functionality to put in 3 number values and get out the hex color.

Change the program to take the kind of conversion you want to do.

node index.js rgb 255 255 255

Will print out:

#ffffff

Further

Separate your conversion functions out into separate module file(s).

Further

Add HSL colors.

If the user puts in a hex color, print out the rgb and hsl values.

If the user puts in a rgb value, print out the hsl an d hex values.

Further

Color the output using bash colors: (note this doesn't work on all terminals!)

// set as red
var r = 255;
var b = 0;
var g = 0;

// this special console will create colored output
console.log(`\x1b[38;2;${r};${g};${b}m%s\x1b[0m`, myOutput);

Further

Using some UNIX CLI syntax to be able to take in a number of colors and print out a conversion for each input.

This example gives the result of cat to your program.

node index.js hex $(cat colors.txt)

Further

Give your program the ability to calculate more information about colors.

Output other color harmonies given an input: https://dev.to/benjaminadk/make-color-math-great-again--45of
