The sky turns purple at high y-altitiudes
When flying super-high in creative the sky becomes purple, as opposed to blue. this is best observed by using the /tp command to teleport to a very high y value.
How to replicate:
1. Create a new creative world.
2. /tp to a very high y-value, around 1000000, however the effect can be seen as low as y=5000.

A comment with security level 'global-moderators' was removed.
Confirmed for 15w44a.
Relates to MC-53510.
Note: Couldn't reproduce being unable to teleport to high altitudes. This should be intended.
Some additional information I found:
• I found out the highest altitude of which you're able to move in the Y-axis. It's interestingly enough the specific number of Y=4503599627370496.
/tp ~ 4503599627370496 ~
You won't be able to fly with creative mode over that height. It's like a roof. You are able to fly down. Y=4503599627370496 seems to be the highest point you are able to fly to.
- Now test
/tp ~ 4503599627370497 ~
and try to move in the Y-axis. The only way of moving is by falling, you can't fly in creative to move.
• When you teleport over Y=100000000000000000 the F3 menu begins to show inaccurate Y coordinates(mostly by changing the last four digits). This relates to what the description says (teleport to 10^75 but F3 shows 10E81).
• Over Y=10000000000000000 there seems to be a delay before the coordinate updates when you fall from there.
The highest point you can go to and at same time the coordinate updates when you fall is Y=36028797018963972, which takes about 3 seconds to start updating after you fall.
/tp ~ 36028797018963972 ~
- Fall. Observe the Y coordinate.
/tp ~ 36028797018963973 ~
- Fall and observe the Y coordinate again. It won't update.
• The lowest point you can get outside the world border is at Y=2147483645.
- Be inside the world border.
/tp ~ 2147483644 ~
and then try to get outside the world border by looking at your coordinates.
/tp ~ 2147483645 ~
You'll see that you can go through the world border by some blocks.
Phew. This was a lot of pointless info!

Cannot reproduce. Screenshot pls?
Will post--check in a few minutes
First one (blue); y=130
Second one (purple); y=100000
still in 18a
Confirmed. Also, the sky is already darker at y=256 in 14w20b.
This (bug i think)it appears on ps3,xbox 360,minecraft pe and minecraft pc and i think it is biome lighting change(im not sure!)
Confirmed for 14w21b.
Confirmed for 15w43c.
Confirmed for 15w44a.
I'm very curious as to why this issue was marked WAI. What is the intention for it?
That the sky change color at high altitudes? That's kind of how it works in real life, so I don't understand why anyone would think it's a bug. Also, it helps give the player a sense of motion that's otherwise lacking at high altitudes.
True, but if this were the case wouldn't the sky get blacker?
It gets darker, doesn't it? You presumably never leave the atmosphere though, since the Minecraft world is infinite~ish in all directions. So you never reach the icy blackness of space. There's still atmospheric diffusion, giving the sky a color, rather than it turning black.
what I still don't get about this resolution is that even if the sky is supposed to become purple as you go higher, it's not noticeable within the range of y-values normally accessible in survival. The only way to see this is to go into creative and fly up, get teleported up, or possibly get launched out of a tnt player launcher. What's the point if it's not noticeable?
