Iris appears as a light-skinned woman wearing a golden crown and a light blue strap dress. She is enveloped by a rainbow, with her purple hair making up the top stripe. Coming down from her hair, the blue and the green stripes seem to be attached to her back, trailing behind her. She carries the yellow stripe in her right hand, pulling it across the sky. In her left hand, she holds the orange and red stripes. They flow across her skirt and trail behind her.
Iris' only appearance is when she makes a beautiful rainbow after a storm that Zeus and Vulcan caused.
- Arcus is the goddess' Roman name.
