### The Two-Color Effect Explained
How Duotone Works: A gradient map runs across every pixel's brightness — shadows take one color, highlights take another. The result is the bold, editorial two-tone look made famous by Spotify playlist covers.

10 Presets + Custom Colors: Start from Spotify, Cyberpunk, Sunset, Mono Noir, and six more curated pairs. Or pick any shadow and highlight hex codes yourself. The canvas previews every change live.

Transparency Preserved: Duotone only colors visible pixels. Logos and PNGs with transparent backgrounds keep their alpha channel intact after export — ready for any context.

Shadow vs Highlight Roles: The shadow color fills dark areas and dominates large flat shapes. The highlight color defines bright tones and surface detail. Which one you want to occupy more visual weight is the practical starting point for choosing a pair.

Works Best On: Black-and-white photography, high-contrast portraits, architectural shots, and any image that looks interesting in greyscale. If the greyscale version is interesting, the duotone will be too.

When to Skip It: Colorful flat illustrations lose their color identity and look muddied. Very low-contrast images with only midtones produce flat results. Run the greyscale test first — dull greyscale means dull duotone.

### Frequently asked questions
Q: What is a duotone effect?
A: A duotone maps the brightness of every pixel between two colors — shadows take one color, highlights take the other. Spotify's playlist covers are the iconic example. Great for mood, brand consistency, and modern editorial design.

Q: Can I customize the colors?
A: Yes. Pick any two colors via the color pickers, or start from one of ten curated presets (Spotify pink/purple, Cyberpunk, Sunset, Mono Noir, Rose Gold, Ocean, Forest, Plasma, Sepia, Midnight) and tweak from there.

Q: Does duotone work on logos with transparency?
A: Yes — transparency is preserved. Duotone only colors the visible pixels, so logos exported as PNG keep their transparent background.

Q: Is the duotone generator free?
A: Yes, completely free. Generate as many duotones as you want and apply them to your canvas at no credit cost. Downloading the result uses the standard 1-credit export.

Q: What's the difference between duotone and a gradient overlay?
A: A gradient overlay paints color across the image at the layer level, ignoring pixel brightness. A duotone maps each pixel's brightness through two colors, so tonal variation — detail in shadows and highlights — is fully preserved. The result looks designed, not painted over.

Q: Can I apply duotone to a photo?
A: Yes — duotone works on any image. It's most striking on high-contrast photographs (portraits, architecture, black-and-white shots). Upload a JPG, PNG, or WebP and the tool applies the effect instantly with no quality loss.
