I really like how they are not just one solid color. There are dark areas near the tip and middle line, and there are lighter areas near the middle. I also love how they have different intensities. One is blue, another is light blue, and another is almost purple. Their contrast with the green leaves, and the light pink flowers next to them really make the color stand out even more. These are really nice looking flowers.
They are quite intricate in colouring really, I like that also because it shows character and personality...yes, even in a plant.
