# Auditing theme color palettes under warm display filters

Check syntax and UI color sets for readability and distinction when blue-light filters are active

[Use with BotBento ](https://app.botbento.com/?ref=usecases&utm_source=botbento.com&utm_medium=usecases&utm_campaign=auditing-theme-color-palettes-under-warm-display)Copy promptShare[Markdown](/text/usecases/auditing-theme-color-palettes-under-warm-display/index.md)[العربية](/ar/usecases/auditing-theme-color-palettes-under-warm-display/)

Opens BotBento. Paste the prompt into a bot; nothing is preconfigured.

- When you askReceive palette configuration
- ThenSimulate channel suppression
- ResultReview color audit report

Evaluate UI, terminal, and chart color palettes against simulated screen filter conditions. The bot parses color tokens, models blue and green channel suppression typical of night-mode software, calculates perceptual color differences, and flags tokens that collapse into indistinguishable shades.

## Prompt to start with

BotBentoRecommended

```
When the user shares theme configuration files or hex color lists, simulate display filter transforms by reducing blue and green chromaticity. Calculate pairwise contrast and distinctness scores across syntax, terminal, and visualization tokens. Flag overlapping shades, suggest alternative values with sufficient separation, and wait for user approval before opening any pull request or updating theme files in the repository.
