It would be very useful to be able to adjust the ground plane color in Terragen Sky. Terragen Sky is fantastic for quickly creating spherical HDRI's for backgrounds and lighting. The dark blue, ocean ground plane isn't great for lighting and it can really stand out through any holes or seams in geometry or on the horizon if the setting is a typical terrain which is most often a lighter, more neutral color(greens, tans, greys, etc.).
Ocean is a fairly uncommon location/setting for CGI, games, etc. so being able to set the color to something more use case specific would be fantastic. Two colors and some fractal noise would be a nice bonus.
