CopyValues Script, Hex Code not accurate

[GregCont]

Hi again Geeks, I'm having an issue with this script, that copy the CMYK values and does it fine but I tried to get the Hex Code in other text layer and it put an Hex Code but not accurately. See Picture attached 

Hex Codes don't match, I just attached the script:

//#target photoshop

// Definir las coordenadas para las tres ubicaciones y sus capas Hex correspondientes

var coordinates = [

{ x: 174, y: 485, layerName: "PRIMARY", hexLayerName: "Hex1" }, // PRIMARY -> Hex1

{ x: 171, y: 722, layerName: "SECONDARY", hexLayerName: "Hex2" }, // SECONDARY -> Hex2

{ x: 168, y: 968, layerName: "TERTIARY", hexLayerName: "Hex3" } // TERTIARY -> Hex3

];

// Iterar sobre las coordenadas para actualizar las capas de texto correspondientes

for (var i = 0; i < coordinates.length; i++) {

var coord = coordinates[i];

// Añadir un color sampler en la coordenada especificada

var colorSampler = app.activeDocument.colorSamplers.add([coord.x, coord.y]);

// Obtener el color en formato CMYK

var cmykColor = colorSampler.color.cmyk;

// Formatear los valores CMYK para mostrar

var theColor =

Math.round(cmykColor.cyan) + "," +

Math.round(cmykColor.magenta) + "," +

Math.round(cmykColor.yellow) + "," +

Math.round(cmykColor.black);

// Convertir CMYK a Hex directamente

var hexColor = cmykToHex(cmykColor);

// Eliminar el color sampler para no dejar marcadores en el documento

colorSampler.remove();

// Buscar la capa de texto correspondiente para CMYK

try {

var textLayer = app.activeDocument.artLayers.getByName(coord.layerName);

// Verificar si la capa es de tipo texto

if (textLayer.kind == LayerKind.TEXT) {

// Pegar los valores CMYK en la capa de texto

textLayer.textItem.contents = theColor;

}

} catch (e) {

alert("No se encontró la capa de texto con el nombre: " + coord.layerName);

}

// Buscar la capa de texto correspondiente para Hex y asignar el valor

try {

var hexLayer = app.activeDocument.artLayers.getByName(coord.hexLayerName);

if (hexLayer.kind == LayerKind.TEXT) {

hexLayer.textItem.contents = hexColor;

}

} catch (e) {

alert("No se encontró la capa de texto con el nombre: " + coord.hexLayerName);

}

}

// Función para convertir CMYK directamente a Hex

function cmykToHex(cmyk) {

var cyan = cmyk.cyan / 100;

var magenta = cmyk.magenta / 100;

var yellow = cmyk.yellow / 100;

var black = cmyk.black / 100;

// Convertir CMYK a RGB

var red = Math.round(255 * (1 - cyan) * (1 - black));

var green = Math.round(255 * (1 - magenta) * (1 - black));

var blue = Math.round(255 * (1 - yellow) * (1 - black));

// Convertir RGB a Hex

return "#" + ((1 << 24) + (red << 16) + (green << 8) + blue).toString(16).slice(1).toUpperCase();

}

CMYK to hex probably wont be that useful. There are multiple ways to have, say, black (rich black has the other ink colors as well.) I'd probably make a temp copy, convert to RGB, and sample that temp file for the values.

I would argue that the Color Picker Hex display is incorrect in this representation of the colour values, as the document is CMYK. Notice how there are no radio buttons next to the CMYK fields. 

Hex is a subset of RGB.

CMYK (via ICC PCS) > RGB > Hex

I just found a solution having other Script getting the HexCode without converting from CMYK. Just Straight from rgb as you tell. So I combined both scripts and use it as a buttom on Action Panel.

Not just straight from RGB, but straight from sRGB.  That's how hex is normally used, by convention.

If hex numbers refer to, say, Adobe RGB, you'd get different hex codes for the same colors. This is color space specific. Which, BTW, also applies to CMYK.
