Colour Catcher Sheets

Some makes when you use them come out the washer discoloured. That makes you feel satisfied that they are doing their job.
The ones I am using at the moment come out startlingly white. This makes me wonder if they are fakes.
Does anyone have any knowledge about them?

I have only used Dylon and Dr Beckmann and they both always come out discoloured.

At the moment I am using Colour Magnet. Its a case of grab them when you can, as they are not easy to find here.

Never heard of them, my local Sainsburys does both of the others, so I get whichever is cheaper.
