Simply down to the act that the camos are simple single colours foor every nation. They are simple recolours while camos can still stay as cost for gold due to the unique patterns. Maybe add new ones in the future or improve the current one as some of them have stretching and it just looks odd.
that’s very optimistic…
but i would at least make basic colors ( such as green, brown, tan and white/gray ) buyable for silver.
no more than 10k .
alternatively, i’d be in favor for the camouflage you buy, gets added to all your vehicles.
so we can rise both the price in gold ( or keep it the same ) and make the camouflage up to 50k.
but, that’s also optimism.
or let’s say, like in war thunder, you can unlock SOME of them if you do a lot of play?
I’m not buying any (more) camo’s until the campaign/theatre is selectable.
And the price should be lowered obviously.
Currently, this camo buying system makes no sense at all.
Yes if you buy a yellow camo for desert, your tank will be send to a campaign with only snow, and vice versa.
This is a BR 2 vehicle, it can appear in many campaigns, so I would like a yellow camo for Tunisia, white for Bulge, green for Normandy, and so on…
Just think of all the 
you will make,
