Blue Hair Don't Care

I've launched a new event for BCHC Charity for this month, Wear Blue For BCHC, which will be happening on 27th September (feel free to prod me if you want to take part!) I've picked up 2 wigs, one daft and one sensible; can you tell which one this is? XD I'm really hoping the day goes well, mostly because I really want to raise a bunch of money for the charity, but also partly because I don't want to be the only giant blue idiot at work!
