color rendition depends on the coatings,
dont mix it up with brightness,
did you compare them side by side?
are the 12x and 10x50 SV of different age?
I know that on Allbinos.com the tested samples of 10x42 SV and 8.5x42 SV have somewhat different transmission curves,
In the newer Swaro ATX scopes the colors are a bit warmer/neutral than in the older ATS scopes.
(and perhaps newer ATS scopes will get same coating..??)
Don't know if this coating change has trickled down to the binoculars
but I guess it seems reasonable. Swaro will probably try to keep the same color rendition
in all off their top of the line products.
In that case the 12x50 might could be a newer sample with the latest coatings
than your 10x50?
but now I'm speculating..
For me, color rendering in optics is somewhat complicated,
since the eyes/brain have its own "white balance" features….
as well as brightness adjustment/ND-filters...
and they are very easy to trick…
so don't ever trust your eyes, ,-)
newer understood people who think that binoculars can be too bright…
I don't want built in sunglasses in my binos...
and if you do, just use ND-filters or shades….
