The further away an object is, the more it's colour fades out.
I think the distance for loss of colour of the Earth is about 60,000 miles, although don't hold me to that.
When this far away, the Earth is mostly just white, not blue.
You might want to rethink that statement.
Color is the different wave length of the electromagnetic energy we call "light".
The brightness of that light can fade with distance, but if the light is at a wavelength to show the color green, it will still be green.
Even at almost 2,000 lightyears away, the pink in Orion's Nebula can be see (with a camera, this one film, not our eyes, as it's too dim):
Go out in the night sky and look up at Mars with your eyes: it will look orangish red, even though it's tens of millions of miles away.
So it's the intensity of the light....and our eyes. However, if you gather enough of the light (IE use a camera with a long enough exposure) and
there is color there, you'll see it.
