Besides Army Green, any other color you would like try for HD20?
I would recommend to NOT producing any shiny, bright-colored versions of HD20, i.e. no flashy green, no blaze orange, no sky blue etc.. It just doesn't work well for a head lamp or tool lamp, in my opinion.
If I had to choose I would go for "Urban Camouflage" or "Desert Camouflage" to use as a matte camo pattern for some of Wurkkos's flashlights, especially for HD20 when attached to a protective vest, a combat helmet or hat.
So far, a few manufacturers have offered these kinds of "anodizing" like Wuben, Olight or Klarus. However, it will for sure increase the price a little bit.
Here's a draft picture of Sofirn's LT1 with camo pattern. Unfortunately, chances are negligible that this version will ever be made.
Nice camo pattern!
Your draft pic looks really nice. 
Thank you raccoon city. But all credits go to TLF member Andreas "oOFOXOo" who is a genius in Adobe Photoshop and who helped me to create some suggestions for the next LT1 colors. ;-)
BTW: Lately, I was lucky to get Resident Evil 1-6 as a box version for a true bargain price on Amazon. I can't wait to finally watch The Final Chapter. :-)
I’m looking forward to having one, spot + flood would be perfect for bike rides and trekking in the mountains without having to use two flashlights at the same, and the autonomy offered by a 21700… 
I hope it will be available on Amazon.ES.
Since Wurkkos did some unexpected last minute changes in HD20's user interface, I took the liberty to do some editing of the manual in order to reflect the actual UI that was implemented into lights of batch #1. The revised parts are highlighted with red text on yellow background. Sorry for any inconveniences you may have encountered by following the UI stated in the original manual.

Just fyi, I measured the HD20 at 87 grams, far less than the 130 grams specified (no battery). I weighed the HD20 and the head strap at 132 grams. More details with pics here: https://budgetlightforum.com/t/-/62231/296
That's a confusing spec - if it was taken with the strap then it should be mentioned. Otherwise it seems better to use the weight without the head strap. Everyone thought this light was too heavy because of what was specified. I looked and couldn't find the true weight in any of the threads or reviews.
That’s a good catch Tom E.
Weird - all this attention and reviews, don't understand.

Thanks for showing the difference of the actual implemented UI…
Are there already different UI between different batches (initial batch vs current batch) of HD20 or is the UI still the same as the one you marked above?
I don’t know. I try to get in touch with Wurkkos to find out.
Green color available now, and version update on compatibility of USB-C charging and reverse charging
