So, Ziggy made a thread a while ago, about the beigification of the galaxy. It's something I had noticed myself - but visual proof is hard to come by as quite often most planets I have footage of are tens of thousands of light years away, so it's difficult to get back to do comparison shots.
I've gone through a load of my old videos and noticed just how varied and impressive many of the planets were. Today, I just cannot find that variety in game. Most of the planets are indeed beige.
I then came across a clip that contained a system map from version 2.0 of the game. So, I went and made a side-by-side comparison with version 2.2.

So it's true - things have turned beige. And not only that, but entire stars have also changed class!
EDIT: This is the first planet in the system from the map in the first video. This is how the surface appeared in 2.0:

I haven't got a comparison unfortunately. But anyone who is able to get there at least has something to compare to.
EDIT 2: Here is another planet comparison 2.0 to 2.2 - you can see the colours have totally changed:
