Also Riot Nurse, to add "evidence" and to support my arguement, here's some quotes that was upvoted quite a lot in surrenderat20 when the news of the new nidalee skin color came out. That's a lot of disappointment and money staying in pockets.

"Hey Moobeat, I was wondering why did they change Nidalee's skin tone? A lot of her skins like Snow bunny Nidalee, Bewitching Nidalee and Headhunter Nidalee her skin looks pale in comparison to her original model. Why the change? How come her skin is not consistent to all her other skins? I personally feel her paler skin made her pop out, now her skin blends in with her outfit..."
"Yeah, it used to look like red with pale skin, now it just looks like brown with brown. I don't see anything wrong with giving Chinese-colored skin to a Chinese based skin.
I was planning on getting the skin, but now it looks a little plain. She reminded me of those warrior women on Avatar: The Last Airbender in a way, but now she reminds me of Nikki Minaj in one of her music videos"
"I too think to avatar, when I first saw the skin, I was happy but now Idk I don't like the skin that much, it's because her skin do not fit to her skin tone."
"Yeah, I guess it's just my preference since I like how it contrasts with the red armor and how it reminds me of Avatar.
I really wanted the skin before, but now I'm not sure if I still want it. I just don't see anything wrong with leaving it how she was before"
"I was wondering the same thing. I like the paler tone better. It stands out against her armor, and I think she matches her cougar form better. I was was waiting for this skin... now it's just "blah" to me. I went and bought RP just for this skin. Unless it changes back, I think I may just wait for the next batch of skins to be released and pray there is something I actually like."
"Same, when I first saw the skin I was so hyped. It's one of the prettiest ones I've seen in Lunar Revel. I honestly couldn't wait for February. This isn't a matter of that the tan skin is unattractive (original Nidalee is gorgeous), it's just the colors of her outfit and now her darker skin are blending in too much together...and it just really looks flat now. The pale skin really made it pop. I hope they go with a between skin tone to satisfy the people who like her darker, and those who like her just a bit brighter so everyone can enjoy this beautiful skin. I'd prefer the original pale but who knows."
