These are not in order.
1) Lightning Dust and Sunshower Raindrops
Why did I put these two together? It's simple: similar color palettes.
While the opposite of orange is blue, those colors on these ponies are tinted and/or warmed.
There's just something about these simple designs that I absolutely love.
2) Thunderstruck
This design is awesome. The slightly cooler hue of purple makes this pony seem more mature yet still spunky. Fitting for a teenager (lol).
The yellow streak
