Magento: How do I cache module output?

I have seen the wiki page on how to cache block output on Magentocommerce.com and read an inchoo article on how to do it. However, I want to cache the output of a module that isn't tied into a product.

What my module does is load up the colour entries in an attribute, does some maths on them to sort them by tint/hue/brightness etc. and then outputs a colour picker (that can be used on product pages).

I have other modules that could also benefit from cache control, again these are not particularly tied to a product. Hence, in the tutorials, where there is this:

'cache_tags'     => array(Mage_Catalog_Model_Product::CACHE_TAG), 'cache_key'      => $this->getProduct()->getId()

do I just stuff in any old numbers?

You should use custom cache tag and key

'cache_tags'     => array(Yourpackage_Yourmodule_Model_Yourmodel::CACHE_TAG) 
'cache_key'      => '<your cache key here>'

If I got you right, your block output is always the same, that's why you can use attribute code as cache tag and attribute id as key (for example).
