Filtering a recordset more than once on one page?

Question

Although I'm a relative noob to php I'm ok to create recordsets and display them on a page and other more compicated recordsets using DW CS4 I'm strangely stumped how to do the following (although i'm sure i've done this already before!):
As an example, say I have a page 'pens.php' and have created a recordset 'rsPens' that displays all pens from the database in a repeating region that  displays as follows:
Available Pens
blue pen
red pen
yellow pen
green pen  ...etc
How do I create a clickable link (either text, radio button, drop down list etc) that can filter any of the colours to display only one colour pen like this:
Available Pens
red pen
I'm thinking the url would look something like this: www.mysite.com/pens.php?pencolour=red but not sure how to edit the recordset. I think the answer will probably amaze me with it's simplicity but I've frazzled more than a safe amount of brain cells already and don't have many left!!
TIA...Andre

Hi
This is more a question for the 'application' development' section of the forum, but here goes -
If you use an isset section in your php code to check for the color selection and a link directing the form action to your php code page that sets the value via a $_POST for your color selection, would this not do what you wish?
