Prismatic ribbon: a rainbow prism light effect arched over deep indigo
This is where Spectrum Flow Lab starts: a ribbon field bent along an arch, colored with the full prism spectrum and tilted 30 degrees over a deep indigo backdrop. Glow sits at the midpoint of 50 and Grain at a barely visible 4, so the band reads as clean refracted light instead of a texture. It suits hero sections that want one confident sweep of color and plenty of dark space for a headline.
Make it yours
Widen the band for a softer hero
Spread starts at 50. Push it toward 80 and the ribbon swells into a broad wash of color; pull it to 20 for a thin, precise line of light that stays out of the way of text.
Swap the arch for an S-curve
Curve is set to arch, which frames whatever sits underneath. Choose s-curve for a band that snakes across the frame, then raise Curvature above its 55 to exaggerate the swing.
FAQ
What makes a light effect look like a prism?
Two things: the full rainbow order of colors and the fine parallel lines inside the band. Here the prism spectrum supplies the colors, and Complexity, set to 4, draws the striations you see when light splits through glass. A dark Light color does the rest by keeping every hue saturated.
How it works
Pick a field and a curve
Choose one of 5 fields and 4 curves, or start from one of 17 looks such as Prismatic ribbon or Iridescent halo.
Tune the light
Adjust scale, bend, spread, detail, angle, glow, grain and speed.
