Color Check for String

I was wanting to see how I would go about validating a string as a color. I am using a command to change the color of the member's role and if you input anything that isn't valid it kills the bot. I am mainly wanting something like new Color(colorString); and checking if that isn't null before passing it to the role.setColor() function

export const colorPredicate = s.number.int
    .greaterThanOrEqual(0)
    .lessThanOrEqual(0xffffff)
    .or(s.tuple([RGBPredicate, RGBPredicate, RGBPredicate]))
    .nullable.setValidationEnabled(isValidationEnabled);

export const colorPredicate = s.number.int
    .greaterThanOrEqual(0)
    .lessThanOrEqual(0xffffff)
    .or(s.tuple([RGBPredicate, RGBPredicate, RGBPredicate]))
    .nullable.setValidationEnabled(isValidationEnabled);

This is what is used inside @discordjs/builders using @sapphire/shapeshift

That will help for the hex, I supposed I would also have to make an array of valid strings to check if it is one of those as well.

Going to give it a try lol I had this:

                try{
                    role.setColor(color);
                } catch(err) {
                    console.error(err);
                }
                interaction.reply("Your color has been changed");

                try{
                    role.setColor(color);
                } catch(err) {
                    console.error(err);
                }
                interaction.reply("Your color has been changed");

But it was printing the error and still crashed the bot I have it working now so its alright lol
