Add iridescent foil color
The filter generates three phase-shifted color waves and projects them across the image at the selected angle. Their red, green, and blue peaks form a moving spectrum rather than a static rainbow image, so the color order and spacing behave like light interference instead of a painted gradient.
Iridescence controls how much of the spectrum mixes into the source. Spectral bands changes the repetition rate, and Foil texture adds fine seeded brightness variation.
Angle and band spacing
Rotate Foil angle to follow the main edge or surface in the photo. Fewer bands create broad color fields across products and portraits. More bands produce narrow reflective stripes suited to abstract graphics and card-style artwork.
Strong iridescence can flatten the original color relationships. Lower it when skin tone or brand color must remain recognizable.
Example: product shot on foil
For a sneaker or bottle on a plain background, set Spectral bands near 60 and align Foil angle with the product’s longest edge so the stripes appear to wrap it. Iridescence around 45 tints the highlights while the object’s own color still leads. Add Foil texture last, around 30, so the sheen sparkles without turning into noise.
For a full holo-card treatment of artwork or type, push Iridescence past 70 and let the spectrum take over; the source then acts as a luminance map for the foil.
Real foil, simulated
Physical holographic foil splits light through microscopic ridges, so its colors shift as the card tilts. A single image cannot animate, which is why the seed and angle matter: they choose the one frozen moment of that shimmer you export. Rendering two or three exports with different angles and cross-fading them in a video editor is a cheap way to bring the motion back.
