Spectral prism: a white nautilus with rainbow edges on black
Spectral prism draws the Shell structure in white light on black, so the nautilus spiral glows like a lit glass sculpture. Iridescent edge sits at the maximum of 100, yet the rainbow stays confined to the edges, because Edge contrast 85 dims the face-on filaments and the thin-film hue only shows where the tube turns away. The result is a pale, almost colorless body with spectral fringes tracing its outline.
Make it yours
Spread the spectrum
Lower Edge contrast to about 45 and the faces brighten, letting more of the prism color wash across the tube instead of staying a thin line on the outline.
Add a soft halo
Membrane edge softness at 35 keeps the glow tight. Raise it to 70 for a wide bloom around the spiral, closer to a long exposure of a glowing object.
FAQ
How does Spectral prism differ from Pearl chamber?
They share the Shell structure. Pearl chamber tints bone paper with a soft pastel sheen at medium settings, while Spectral prism glows on black with the strongest fringe and a high edge contrast, so its color sits only on the outline.
How it works
Pick a structure
Start from one of 16 looks such as Plum smoke, Aurora curtain or Spectral prism, or choose one of 8 flow structures: tide, iris, wings, cells, division, shell, curtain or corona.
Tune the light
Shape it with fold complexity, fluid tension and filament density, then set translucency, edge contrast, the iridescent edge and membrane edge softness for the glow. Drag the artwork to place it.
Color and use it
Set the background, first, second and light colors, press Play for a seamless loop of about 17 seconds, then sign in with a free UX Pilot account to use it on the canvas or export it.
