Hey guys... Here's a more realistic version of a minecraft globe, with the dark-green colour contrasting a little extra to the deep, ocean water. Even though earth is actually in space and all, which I guess would've been easier to symbolize with a black base, the earth figure stands out a bit more within all of the white, which is why I chose white instead of black. That's MY opinion though; go check this version out if you want a space-y background!
