No problem at all.

I use this part of the code to convert HEX to RGB.

function getsub_acf_rgb($field, $id) {
	if ( function_exists('get_sub_field') ) {
	$hexx = get_sub_field($field, $id);
	// extra sanity check that we're dealing with the hex flatuicolorpicker
	// in #NNNNNN format that ACF/WordPress/Iris colorpicker returns
	if (strlen($hexx) == 7 && substr($hexx,0,1) == '#') {
	$rr = hexdec(substr($hexx,1,2));
	$gg = hexdec(substr($hexx,3,2));
	$bb = hexdec(substr($hexx,5,2));
	return $rr . ', ' . $gg . ', ' . $bb;
	}
	else {
	// provide a default in an emergency
	return "128,128,128" ;
	}
	}
	}

	function acsf_rgb($field, $id) {
	echo getsub_acf_rgb($field, $id);
	}

function hex2rgb($hex) {
	$color = str_replace('#','',$hex);
	$rgb = array(
	   'r' => hexdec(substr($color,0,2)),
	   'g' => hexdec(substr($color,2,2)),
	   'b' => hexdec(substr($color,4,2)),
	);
	return $rgb;
 }

but I wonder how I can pass the value of RGB to HSV
