I appreciate all the replies and insight! I've never been very adventurous when it comes to trying new colors both in soft plastics and in hard baits. I've always used Green Pumpkin, White, and Black, for soft plastics. Other colors I've tried just didn't seem to work.

 

I went down to the river yesterday evening and got a Goggleeye on the new color. It was a pretty slow bite for me yesterday. But there was a lot of other people fishing that section too.

Watermelon red is almost as good as purple. Almost. 

Watermelon Red is especially good around grass in clear water . 

I use it a lot, mostly because green pumpkin sells out frequently and watermelon red is usually the next best thing.  
 

Like others have said it works best form me in clear water, preferably in sunny conditions.
