Renoir

A modern Android application built with Jetpack Compose and Kotlin that acts as an advanced Material You (Monet) theme designer, generator, and applier

This app allows users to visually design a Material 3 dynamic color scheme from a single seed color. It leverages the material-kolor library (a port of Google's material-color-utilities) to accurately map colors to the HCT (Hue, Chroma, Tone) color space and generate cohesive tonal palettes.

Once a theme is designed, the app generates a shell command that uses Android's internal settings put secure theme_customization_overlay_packages command to apply the theme system-wide. The app can apply this directly if granted the WRITE_SECURE_SETTINGS permission via ADB, or it can use Shizuku to apply the theme on-device without a PC

To apply themes, you must grant the app permission using ONE of the following methods:

Option 1: Shizuku (On-Device, No PC Required) Install Shizuku from the Play Store. Start the Shizuku service (via Wireless Debugging or root). Open Renoir and click "Apply Theme". You will be prompted to grant Shizuku access.
