... the default size setting should be XL and the default color shown should be BLACK.

Respectfully disagree. It may make sense in your limited scenario. But there are lots of instances *not* involving shirts where this makes little sense.

If I add an "Oval Beige mixing bowl" to my shopping cart, then go shopping for dinner plates, "Beige" may be the wrong color for my dinner table, and "Oval" might be invalid. The customer would need to clear the "Beige" filter to see the correct results... an extra step.

Even in the clothing genre, if I buy "black" slacks for church, should my selection of summer shorts default to "black"?

Until the spontaneous telepathic interface is perfected, I feel that your suggestion of "sticky filters" can lead to unintended results in all but a few specific scenarios.
