Up until a day or so ago I had always thought of miniature iris as reticulata and blue in color. Last year though I purchased a mixed bag of miniature iris and the colors are far from dark blue. Mine include a burgundy/maroon color and a delicate pale blue.

When I went back to the catalogue and checked my order, it seems that the pale blue are a variation of the reticulata and, although the page does list an I. histrioides which looks definitely like my little guy. Matching pictures is the only way I can assess this because I have not idea how the it is different from a reticulata except in color.
