How to get functions.php to talk to options.php

Question

When you save an array of data in an option, WordPress serializes it to save, then when you use get_option, it gets unserialized back into the original array, so it can be accessed as you’d access any indexed array without keys in php:

original option added:

$hsv = array('hval','sval','vval');
add_option('hsv', $hsv);

then, to access this data:

$hsv = get_option('hsv');
echo 'h value is ' . $hsv[0];
echo 's value is ' . $hsv[1];
echo 'v value is ' . $hsv[2];
