Request for direct 12 digit hex out put for Tuya smart LED

[dane-k-1981]

I would like to ask if its possible to add a 12 digit HEX color output/input as all my Tuya Smart 5CH Led using it.
At the moment I using decoding on input and output to change to right data.
Am a beginner so my code might be longer then it should be, but this is only way I know to make it work.

Output:
var hue = msg.payload.h;
var saturation = msg.payload.s10;
var value = msg.payload.v10;

// Remove decimal places "issues with long decimals"
var integerNumber = Math.round(hue);
var integerNumber = Math.round(saturation);
var integerNumber = Math.round(value);

// Convert decimal to 4-digit hex
var hueHex = hue.toString(16).padStart(4, '0');
var saturationHex = saturation.toString(16).padStart(4, '0');
var valueHex = value.toString(16).padStart(4, '0');

// Format the HSV-A to HEX color string
var hsv = hueHex + saturationHex + valueHex;

msg.payload = hsv;
return msg;

To get 12 digit HEX to send to Tuya

Then from 12 digit hex from Tuya to HSV

payload.dps["24"] = 000003e803e8

var hexCode = msg.payload;

function hexToHsv(hex) {
// Remove the "#" symbol from the hex code
hex = hex.replace("#", "");

// Convert 12 digit hex to HSV
const h = parseInt(hex.slice(0, 4), 16);
const s = parseInt(hex.slice(4, 8), 16);
const v = parseInt(hex.slice(8, 12), 16);

// Convert RGB to HSV
//const [h, s, v] = convert.rgb.hsv(red, green, blue);

// Return the HSV values
//return { h, s, v };
return "hsv(" + h + ", " + s + ", " + v + ")";

}

const hsv = hexToHsv(hexCode);

msg.payload = hsv;
return msg;

// Input data string
var dataString = msg.payload; // Replace with your data string

// Extract values from the string
var values = dataString.match(/\d+/g);

// Create an object with properties h, s, and v
var dataObject = {
h: parseInt(values[0]),
s: parseInt(values[1])/10,
v: parseInt(values[2])/10
};

// Output data object
msg.payload = dataObject;
return msg;

So I get data to send back to color-picker.

Hope its possible to add. Thank you in advance for your time.
