Hexadecimal color to RGB color JavaScript
We are required to write a JavaScript function that takes in a hexadecimal color and returns its RGB representation.
The function should return an object containing the respective values of red green and blue color −
For example:
hexToRgb('#0080C0') should return 0, 128, 192The code for this will be −
const hex = '#0080C0';
const hexToRGB = hex => {
let r = 0, g = 0, b = 0;
// handling 3 digit hex
if(hex.length == 4){
r = "0x" + hex[1] + hex[1];
g = "0x" + hex[2] + hex[2];
b = "0x" + hex[3] + hex[3];
// handling 6 digit hex
}else if (hex.length == 7){
r = "0x" + hex[1] + hex[2];
g = "0x" + hex[3] + hex[4];
b = "0x" + hex[5] + hex[6];
};
return{
red: +r,
green: +g,
blue: +b
};
}
console.log(hexToRGB(hex));Following is the output on console −
{ red: 0, green: 128, blue: 192 }
