iKCAL

iKCAL is a root module that lets you apply presets for KCAL (Kernel Color Adjustment / screen color calibration). It modifies sysfs nodes like /sys/devices/platform/kcal_ctrl.0/kcal (or similar) to adjust red/green/blue gains, saturation, hue, etc., for better color accuracy, warmer/cooler temperatures, vibrance, or accessibility (e.g., color vision correction).

Features

• Several built-in presets to choose from (exact list not detailed in README; users select via the included ikcal command).
• After installation, run su -c ikcal (or ikcal in a rooted shell) to open a menu and apply a preset.
• Reversible — uninstall the module and reboot to reset colors.

Requirements

• Kernel with KCAL support (most custom kernels on Snapdragon devices; requires Linux 3.10+ kernel).
• Root via Magisk 20.4+ (or equivalent KSU/APatch).
• Recommended: Latest BusyBox.
• Not all stock kernels support KCAL; check with cat /sys/devices/platform/kcal_ctrl.0/kcal (if it exists and is writable).

Installation

1. Download the module zip from the official source: https://www.pling.com/p/1996119/ (primary download link) or GitHub repo.
2. Install via:
   • Magisk app → Modules → Install from storage.
   • KernelSU/APatch manager → Flash the zip.
3. Reboot.

Important notes & warnings

• Only works on KCAL-supported kernels — it will do nothing or fail silently otherwise.
• Use responsibly — extreme presets can make the screen look unnatural or washed out.
• No bootloop risk mentioned; changes are applied post-boot via the module scripts.
• Report bugs via the author’s Telegram group: https://t.me/raidenprjktsgroup
• Credits in README go to preset contributors and templates like MMT-Extended and mod-util.

The GitHub repo has no published releases (as of latest checks), but the source is public with customize.sh, module.prop, and scripts. The module.prop description reads: “Personalize your device for a truly one-of-a-kind experience. Usage: su -c ikcal.”

If your device/kernel supports KCAL, this is a simple way to tweak display colors without flashing a new kernel. Test carefully and back up first. Let me know if you need help checking KCAL support on your device or troubleshooting!
