Carpets that don't show the dirt?

[zookeeper]

I seem to be hoovering the dark red carpet on the stairs and landing every five minutes - can anyone suggest a colour/type of carpet that won't show the dirt?

Is it worth spenidng money on wool carpets? are they all they're cracked up to be?

1 with lots of blended colours and patterns.

I've just been through carpet buying & was advised to by 100% artificial fibre,as the stains can't soak in & can be mopped straight up.Was also advised against looped pile,as it collects more grime & it is harder to hoover out.You could do what my friend did & get as load of samples & throw biscuits on them to see what showed up & what didn't!

what a brilliant idea - dare I try it in Allied Carpets?
