Mermaid Tail Colors?

[Mermaid Clara]

Hello, I'm having trouble on deciding what colors I should choose for my Mernation tail... I'm debating on getting the single color or the multi-color tail, but it depends on how much money I can save.
For the colors I've been debating between shades of green or orange... Its been really hard to choose because I've been going back and forth between the two, but i have an picture I found to which I really like and decided to try and replicate with my silicone tail.

What is your opinion on my inspiration for my tail? Should I just use shades of green in the coloring scheme of the picture or should I use orange?

According to Raina, orange color pops out more underwater. I can vouch for this theory as I have an orange fabric tail, and out of the three colors that I have, orange is more eye catching in the water and out of it.

why not green AND orange? you could replace the purple in that pic with orange

My tail is green and orange. I went through the exact same process. Was thinking lilac and the tips but then decided that orange would pop more.
