@Laura This is a difficult choice. I like option 1 because it looks like a natural sunset, but option 3 is more blue and I love blue 
I'll have to think about this before I submit a feedback form.
Option 1 is pretentious. Life isn't always bright and beautiful.
Option 2 is less pretentious.
Option 3 appropriate. It's more natural, realistic and pleasing to senses. Not too light, not too dark. Just fine.
@hopefulsophy Option 1 looks exactly like the sunset where I live. I don't think it's pretentious when it's realistic.
@WaterfallLily
okay
2 or 3 .. design looks very nice .. i love it😉
I'd choice the 3rd option
Option 3 for me
There's something about pastel blues/purples that really calm me!
Option 1 preferred. Color saturation is good.
Option 2 is okay, but it feels a bit dull.
Option 3 doesn't jive with my eyes at all. The visual message is confused. Is it sunrise (bottom half) or twilight (upper half)?!
Either 1 or 2. Option 3 in my opinion isn't as good as 1 or 2.
@NeckRomancer Final choice is 2
All of them are nice but I like option 1 best because of the turquoise :-)
Option 3 is better
Option 1 has a more calmer feel :)
