Koh Tao - two wire necklace

For this piece I wanted to use two contrasting colours as I was interested to see how they would actually work. I decided to use the orange colour as a subtle colour as I felt it could overpower the whole piece. I actually had in mind a picture I had taken on a scuba diving trip to Koh Tao. In the picture its a deep blue background with 2 yellow butterfly fish about to meet over the brow of a large undersea rock. Although they were yellow, for some reason in my mind I had them as a vibrant orange. Here is the result:

I also made the bracelt to match the necklace this time, I felt very proud of this piece :)

Second piece

When doing this colour scheme I wanted to do something in cool colours. I had no particular thoughts in my mind but I have always liked the combination of green and purple so was using that idea as a basis. I wanted to add something as an extra dimension so I decided to include some blue. I like the combination but cant decide on what it makes me think about....what do you think? What could I call it?
