Which Yinhe Apollo rubber do I have?

[Guitarmaker]

I have Yenhe Apollo rubbers fitted FH and BH, and I like them a lot. I want to buy more the same but see there are different sponge hardnesses available. Is there a way of telling which hardness I have?

PS I now see the red has red or orange sponge and the black has blue sponge.

it's sometimes printed on the back - but not always!

Yes, I'd heard about this. But I'm reluctant to pull the rubbers off, I always struggle to get them back on properly aligned with the bat.
I've been looking up Yenhe sponge colours, but so far found nothing.
