True "Jungle pastels" are more of an abnormality than anything. The "jungle" pattern has never really been proven to be genetic. Your best bet if you're looking for a darker pastel than the lemons is to try and find a nice bell or graziani line pastel. I have one Bell right now and he's got some amazing colors which he's holding onto quite well! Looks like you've got a great collection already though . Have you thought about maybe a cinnamon or a black pastel female to try and make some supers? Then you could put your Black Pastel male to your spider once they're up to size and try for black pastel bees (?) and hold back one or two to pair with a nice pastel to try for black pewters, black pewter bees, pastels, black pastels, spiders, bumblebees lol that would be a great pairing and gives you a little time to find a nice male or female pastel that fits your criteria.

Jenea Woods at Guardian Reptiles has a couple of nice bell line pastels available I believe and I'll vouch for her being a good girl for sure, I just got 1.1 western hogs and 0.0.1 tri-color hoggie from her today! Great records and everything was packaged perfectly . Sorry shameless plug for my girl Jenea.
