Converting a string of hexadecimal color into hexadecimal format using JavaScript

I wrote a function that converts a musical note into a hexadecimal color value.

const colorFromNote = note => `0x${note}${note}${note}`

For example, when 'C4' is passed in, the function returns 0xc4c4c4. Unfortunately, this approach doesn't work with Three.js since it requires an actual hexadecimal parameter, not just a string representation.

Existing solutions focus on generating hex codes from color names, but I specifically need to convert a string of a hex code into the hexadecimal value itself.

Answer №1

If you want to change a string into a hexadecimal value, simply utilize the parseInt function:

parseInt(hexValue, 16);

To transform a number into a hexadecimal string (and vice versa):

yourDigit.toString(16);
