Blue noise: an even, pattern-free dither in indigo and lavender
Blue noise thresholds the image against a noise texture whose dots are spread evenly, so the result has no visible grid like Bayer and none of the crawling worm trails error diffusion can leave in flat areas. This preset renders it as a Duotone in deep indigo and pale lavender with Contrast at 20, which reads as a soft, modern stipple. It suits hero images and editorial illustration where a brand tint matters more than retro flavor.
Make it yours
Add tints between the two inks
With Levels at 2, each pixel is either indigo or lavender. Raise Levels to 4 and the Duotone palette gains intermediate tints, which smooths skin and sky at the cost of the stark two-tone look.
Retint it to your brand
Dark color and Light color drive the whole image. Swap Dark color for your deepest brand shade and Light color for a near-white tint of the same hue, then check that the subject still separates from its surroundings.
FAQ
Why use blue noise instead of Floyd-Steinberg?
Floyd-Steinberg is sharp but directional: it can produce streaks and repeating artifacts in smooth gradients. Blue noise is an evenly spaced threshold pattern, so the grain looks uniform across the whole picture and never forms lines. The trade-off is slightly softer edges, which a little Sharpen can bring back.
