Frequently Asked Questions

How does gradient map work?

For each browser-decoded pixel, Vizua calculates 0.299R + 0.587G + 0.114B and linearly interpolates between the selected start and end RGB colors. Alpha remains unchanged. This is a two-endpoint raster transform, not a color-managed gradient map with editable stops.

Is it the same as duotone?

In Vizua, both tools use a continuous linear blend between two RGB colors driven by calculated luminance. The names and preset choices differ, but neither simulates an ink-separated print duotone or preserves source color profiles.

Can I create my own gradient?

Choose any two colors with the browser color inputs or start from one of eight preset pairs. Only the two endpoints are supported; there are no intermediate stops, curves, blend-space choices, or selective masks.

What you can do with Gradient Map — Artistic Color Effects

Map image luminance to a selected color gradient or preset in your browser. Preview the color effect and export the processed raster.

Private by design

Your files never leave your device. All processing happens locally in your browser.

Tips for better results

  • Start with the cleanest source available; a small, blurry, or heavily compressed file contains less detail to preserve.
  • Check dimensions and format before downloading so the result matches the site, app, printer, or platform where you will use it.
  • For large files, close unnecessary tabs and test one representative file before processing a full batch.
  • Open the downloaded result once before sharing it or replacing an original.

Where Gradient Map — Artistic Color Effects fits in a workflow

Use Gradient Map — Artistic Color Effects for one-off adjustments or as a preparation step before publishing, sharing, archiving, or continuing the edit in another application. When batch processing is available, validate the settings on a small sample first and then apply them to the remaining files.
