What does the Oil Slick effect do in Ether-MOSH?

It converts source luminance into animated, noise-shaped cosine color bands and blends them over the original image, creating a flowing iridescent look in real time.

Is the Oil Slick effect a physical thin-film simulation?

No. It does not model film thickness, refractive index, wavelength, reflection phase, or viewing angle. It is a GPU stylization inspired by the colors associated with thin-film interference.

Where is Oil Slick, and what settings should I start with?

Open the FX panel, choose Color Chaos, and add Oil Slick. Start at 0.45 Amount and 6 Frequency, then tune Frequency to the source's tonal structure.

Can I use Oil Slick for print and projection?

Yes. For print, freeze and soft-proof a legible frame. For projection, use slow visual changes, keep essential information outside the effect, test the real display, and provide a calmer alternate state.

Make the Oil Slick Effect Pass a Sheen Inspection

A practical inquiry into animated iridescence, thin-film optics, and why the Frequency control has turned your portrait into a municipal rainbow incident.

Quick answer

Ether-MOSH Oil Slick maps each pixel's luminance through three offset cosine color bands, then blends the animated iridescence over the source. Amount controls the mix; Frequency sets how tightly colors repeat across tonal values. It is a stylized GPU effect, not a physical thin-film simulation or spill detector. Find it under Color Chaos and start around 0.45 Amount, 6 Frequency.
