This color is suppose to mimic what kind of fish?

A Hitch, (Lavinia exilicauda). It's a baitfish found in some lakes in California. 

Read up on Clear Lake.  The Hitch is the dominant forage base.  Almost all my swimbaits used on Clear Lake are hitch patterns.  That color series works on other lakes where there are no hitch. 

Looks like any other shad to me:  https://www.google.com/search?q=hitch+baitfish&hl=en&tbm=isch&tbo=u&source=univ&sa=X&ei=hi07UbL3JYGS9QT01oGYDA&ved=0CD0QsAQ&biw=765&bih=431

Looks like a whitefish to me

Most Clear Lake Hitch swimbaits have translucent light smoke amber backs with neon blue-charteuse blood line and translucent smoke belly with amber fins, 5" to 8" long. The color should work in a lot northern regions.

To the best of my knowledge there are no Hitch baits in Michigan but the  7" Rago Bvd Light Hitch has been one of my most productive soft swimbaits.      

I also use the Rago hitch colored swimbait with some success here in Illinois.
