>>8057888I chose yellow initially because my very first sub (here from 5 years ago when first built) was loosely based on that one Aquaraiders sub. Stuck with it since yellow is a relatively cheap color; it works well with trans-green (my all-time favorite Lego color) and trans-black; and it fits the theme of underwater mining as a high-visibility color in an otherwise pitch-black environment. I've grown rather fond of yellow as their color, and it's a little late to change the scheme anyway, heh.
Among further anticipated additions there will be an exo-suit mothership, the exo-suits being essentially the ones from Alpha Team: Mission Deep Sea, which will give the miners more options for hands-on stuff. I'm not sure yet if there will be more "ground" vehicles, since driving along the seabed tends to stir up sand and stuff which increases visibility issues and can foul intakes on other craft. If I do end up building something with wheels it'll probably be along the lines of the Hydronaut Crystal Detector, with the big space wheels.
