Utilize the CSS support API for validation purposes.
This particular API allows you to confirm the validity of input data.
CSS.supports(propertyName, propertyValue)
console.log(CSS.supports('color','blue') )
console.log(CSS.supports('color','#FFFFFF') )
console.log(CSS.supports('color','xyz') )
console.log(CSS.supports('color','rgb(0,0,0)') )Of course, I am able to assist with that. Here is a solution:
const str = "This is a #FF0000 red color text and #0000FF blue color text.";
const regex = /#(?:[0-9a-fA-F]{3}){1,2}\b|\b(?:rgb|hsl)a?\((?:(?:\d{1,2}|[1-2]\d{2}|3[0-5]\d)(?:\s*,\s*)){2}(?:\d{1,2}|[1-2]\d{2}|3[0-5]\d)(?:\s*\/\s*(?:0\.\d+|\d+(?:\.\d+)?))?\)/g;
const hexColors = str.match(regex);
console.log(hexColors);
