I purchased 'Riverboat Blues' Iris from a member of the iris society. The bloom on my plant looks like the deep very blue blossom image in the first two photos of the iris society database pictured above. Many of the other photos in the society database including the ones in the garden.org database are showing this plant as a very light lavender color. I'm confused.

Which color is the true color?
Could my plant have been mislabeled?
