I'll definitely post a collection when I can. Currently I've given up because the colors I'm using when making the signs are for some unholy reason not the colors that are showing up in game. Made two signs with the exact same color (just a generic modern theme; but I plan on branching out into more region themes as well); one appears super washed out in-game, the other appears really dark in-game. At first I thought the washed out one was using a lit screen (that'd make sense) but nope... even after double and triple checking that I'm using identical screens they're different shades, and neither are the actual shade I used. Can't be a lighting issue either since even placed on top of each other (90% overlapping) they're completely different shades.
I made them in GIMP, used color picker to double check I used the exact same color; exported them to the exact same file type (JPG) using the exact same export settings. Opened with the default Windows image software they look identical (I mean they have different text and pictures but background color is identical); in game they aren't even close to being the same color. It can't be something I did or my computer since they both look right outside the game; so it must be some sort of bug and it's driving me nuts.
I intend to resume work on them tomorrow. Here's a link to a dropbox (files too large to post); let me know if people are interested in an entire set of these signs. When I'm done I'll also probably post the set to reddit, and organize into more folders when I have more files (Theme, videos, etc.)
