This year I am saving seed from the peas and mangetout that I grew, as they were all delicios and performed well.

Everything went as expected until I shelled two pods of Purple Podded Pea - which usually has green peas - and found navy blue seeds 
 
Is it usual to find different colours like this?

It is if the peas got crossed with another variety thanks to those naughty bees

My Kent Blue pea seed are anything from dark green to dark brown and all shades of grey, so it's quite normal.

The unripe peas are still green though. Pea crossing is very unlikely as self-pollination takes place within an enclosed flower.

Guess the bees hanging around my pea plants didn't know about that part

Strange though that all the other completely dried peas are within the rnage of mottly green and these two pods had really dark navy blue peas. Don't know what colour they were when they were raedy to eat of course

Blue pods and blue peas!! This could make you a fortune. Keep them seperate and see if the breed true.

This is the photo of the seed I posted in the Kent Blue Pea thread, so you can see I'm not telling porkies!

They only turn these colours once they start to dry out.

I believe you (good crop bwt  ) from that one plant 

When 90 % of them are dried hard and greenish grey, and then you have just a few, in two pods that are different ---- made me wonder why?

Especially as peas are usually self pollinating, as you said earlier
