Where are there camo leads?

So the "Mean and Unseen" daily quest wants me to pop 500 Camo Lead Bloons in four days. Anyone have any tips for finding them? It seems like a normal (not mastery) mode game will send me 28 to pop (during round 59 IIRC.) There's that one Special Mission that goes to round 50 where every Bloon is camo, but I think that netted me less than 100 Camo Leads. I'm wondering if I'm missing some obvious way to farm these.

Cheer & thanks!

ETA - I'm not sure if Mastery mode is any better. Whites in normal mode become Leads in mastery, but I think there are even fewer White Camos in normal rounds than there are Lead Camos.

Edit 2 - I just did the special mission, Covert Pops, (again) and made sure to watch the tally - it nets 86 camo leads.

There are only 7 camo leads in mastery stages as far as I'm aware, at round 37.

I think you are doing the absolute best you can at farming them.
