Reproducing/recreating a poster for profit

[alexska]

I am interested in reproducing a poster. From my understanding it would not be legal to make an exact reproduction even if the poster does not state that it is copyright protected. But, what degree can I borrow from the poster without infringing on copyright laws, in terms of the design/format of the poster and the general idea of the poster? Here is some additional information that may be relevant. The poster was originally produced in France. The poster uses a spectrum of colors that the original producer has given names to each color (like Crayola gives names to each of its colors.) The poster is not widely sold or distributed. I greatly appreciate the help.

I thought I would describe the poster as to allow for a better answer. There are rows of the exact same flowers (15 by 6). Each image is computer generated. Under each flower there is a color and a specific instance of the color. For example, Frosty Rain and Pansy (in French).
