Blackberry is my guess as well as it started to come in here this week,the pollen charts tend to give you the colour of the pollen on the flower and it sometimes looks a bit different once the bees have collected it.
Blackberry pollen shouldn't be grey, at least not according to the below chart. See colour around the 'Blackberry' text. I'll check next time I walk by a Blackberry plant.
has someone told the blackberries this?
It is a green grey. More grey than green.
Trouble is, many of the colour charts (printed and online) are way off the mark when it comes to accuracy, a lot of it is due to slight variations creeping in between proofs and final due to printing methods/the way the colours behave on paper etc.
I wondered about this. Does the colour change again when it is mixed and packed in cells?

It's been a bumper elderflower year. I've got my second lot 'steeping' in readiness to turn into wine! 
I'm green with envy. The farmers around here barber the hedges and put sheep everywhere
Plenty bramble here, but, coming from the north west, I never get used to the reality that in this part of the SE there is an almost total absence of inland water.
If you have an iphone, there is an ’i’ under the photo, it’ll ID most plants and animals in your photo.
