Electrical impedance tomography (EIT) is an exciting and emerging medical imaging technology. However, the lack of standardization, namely in colormaps for the different modalities of lung monitoring, is a critical challenge that has sparked ongoing discussions within the community.

To address this, a dedicated EIT colormap work group was formed following the EIT Conference 2023 in Aachen, Germany. This group has convened online multiple times, gradually narrowing down the options for effective colormaps through discussions and surveys.

Still our current methods might at times be too restrictive for the creativity required in this process. To solve this, we developed "ColormapVisualizer," a simple yet powerful web app. This tool allows users to generate custom colormaps effortlessly, helping advance the community consensus on standardizing EIT colormaps.

Key Features of ColormapVisualizer:
- Dynamic and Functional Visualizations: Tailored for ventilation-related, saline bolus, and cardiac/pulsatile imaging.
- Adaptive Colormaps: Automatically adjusts to the data's scale.
- Accessibility Options: Simulate grayscale imaging and colorblind vision.
- Decision Support: Provides information on human perceivable contrast between selected colors.
- Export: Easily export multiple colormap selections for each modality in .csv format.
- Comprehensive Guide: Includes a user-friendly guide to help you get started (see upper left corner of web app).

We invite you to contribute to this standardization effort by sharing your colormap selections.
