Natalie Pleis' collection, "Caelum," is a captivating departure from her signature "Depths of the Earth." While her inspiration still stems from the natural world, "Caelum" explores a softer, more enigmatic side of nature, akin to the heavens. The name "Caelum" itself translates to "sky" and "heaven," setting the tone for this ethereal collection.

Here, Pleis uses a palette dominated by dark hues like deep blues, blacks, dark greens, and radiant gold. This choice of colors creates an atmosphere of mystery and tranquility, reminiscent of the vast sky and distant horizons. The technique remains consistent with her previous work, but here, she masterfully utilizes metallic palettes to achieve a soft, uniform texture, mirroring the serene aspect of the sky.

The titles of the works within this collection, such as "Kalon" (beauty that is more than skin deep) and "Ataraxia" (calmness, untroubled), further accentuate the gentle and contemplative nature of "Caelum." This collection serves as a stark contrast to the rugged rawness of "Depths of the Earth," offering a glimpse into the artist's versatility, as she seamlessly transitions from the untamed earth to the serene skies.
