Blue honda ATF?
 

I know this may sound strange...but I just changed the tranny fluid on
a 2002 accord 4 cyl...and it had a distinctive dark blue tint to it.
This is news to me, I thought it should be dark red if anything. I'm
sure it's the ATF and it smells like ATF, but what about the blue? I
replaced it with Honda Genuine ATF-Z1 which is red. Is ATF-Z1
different than Honda premium ATF or is it the same? I hear people
mentioning regular honda atf and premium so I'm not sure.

Any ideas?

Thanks
