About This Tool

This tool converts images into false color representations by applying a chosen palette to pixel intensity. It is designed for scientists, engineers, and educators who need to highlight subtle contrasts not visible in grayscale.
Conceptually, the tool maps luminance or selected bands to a color gradient. Users select a palette, set a normalization range, and adjust gamma or histogram scaling as needed. The result is a color-mapped image that emphasizes features of interest for analysis, classification, or presentation.
Core value lies in consistency and flexibility: multiple palettes, batch processing, and export in common image formats without requiring desktop software. Use cases include remote sensing band visualization, tissue contrast in medical imagery, or materials identification in laboratory imaging.
Unique differentiators include support for multi-band inputs with weighted mappings, a variety of perceptually uniform palettes, and metadata propagation to support reproducible workflows.

How to Use

Provide inputs: upload an image or specify a URL to the image.
Choose a color palette and set the intensity normalization (min, max) and optional gamma.
(Optional) adjust advanced settings such as histogram equalization or band-to-color mapping for multi-band images.
Run the mapping to generate the false color image.
Download the resulting image and the mapping metadata for reproducibility.

Frequently Asked Questions

Find Quick Answers

What is false color mapping?

False color mapping assigns a color to each pixel based on its intensity or spectral value rather than its visible color. This highlights features such as vegetation health, material differences, or tissue contrast that may be subtle in grayscale and improves visual discrimination for analysis and reporting.

Which image formats are supported for input and output?

Input accepts common raster formats (PNG, JPEG, TIFF) and URL-based images. Outputs are generated as PNG by default with optional JPEG or TIFF exports. Alpha channels are preserved when the palette maps opaque areas, enabling transparent overlays.

Can I use multiple palettes or palettes tailored to specific domains?

Yes. The tool supports a library of palettes and allows saving custom palettes. You can switch palettes to emphasize different features, compare representations, or align with domain conventions in remote sensing, geology, or biology.

Is this suitable for professional remote sensing workflows?

The tool provides visual false color mappings for analysis and presentation. It is not a calibrated processing suite and does not replace domain-specific, sensor-calibrated workflows, but it supports rapid visualization, feature exploration, and reproducible mapping through metadata export.
