While  Scotch_Wusky was happy with the current colors he had and only wanted a few new icons.. I kinda went a little crazy delulu and just pitched way more color alts that he ended up liking!

-- the following was found in a journal near the riverside titled "research log day 5" --
"Each OTR has a designation that seems to be either given to them or created spontaneously by the unit themselves, though they always follow the same format. OTR-Letter, Number, Number. For example OTR-A01 here. No two OTR units ever have the same designation.

We've discovered much on this journey, but it's about time we need to leave. On this expedition we've discovered new fully white OTRs instead of the standard black, we're not sure why some are black and some are white, or even if the colors themselves have significance! Further observation of OTRs is definitely needed... but more and more of my research assistants keep disconnected from the group and going missing. I'm unsure of where they're being kept but I should find them before heading back to the city... But it's late, we need to set up camp and go search for the missing assistants tomorrow.

Maybe we'll get lucky and one of them will be released with some insights into these new OTR variations."

// Head research group 02 has not returned from their week-long expedition.
// Disappearance aligns with research group 01's disappearance.
