An abstract painter, Hardie is fascinated by the way color can create luminosity; and how light, shadow and color interact to achieve the illusion of three dimensions on a two-dimensional canvas. Her work has appeared in Hui No‘eau Visual Arts Center member shows, Maui Watercolor Association exhibits, and in Art Maui.

Colour is what entices Rendel to much of her subject matter—the play of colors on clouds, the variations of hues in the petals of a flower—as do the ephemeral shimmers of light on reflective surfaces, and the yin and yang of contrasts. Her work has appeared in such juried exhibitions as Artists of Hawai‘i, the Hawai‘i Watercolor Society, Hui No‘eau, Art Maui, and the Tri-hue Show.
