Are you looking for replacement pieces or just a match?
I'm sure Homer Laughlin "mixed n' matched" the different colors with the different floral patterns to appeal to the different tastes of a broader range of customers so you might not find an exact photo of your set of dishes.
Like they say, don't re-invent the wheel if you don't have to.
Carnival Glass is an example, many of those patterns are really old Presssed Glass patterns. And to track down some of those patterns its handy to have a set of books by Marion T. Hartung on Carnival Glass which shows nothing but the "pattern" & "shape" of the piece and a description of said: name, maker, etc.
