## What it is
Stillcolor is a lightweight macOS menu bar application that disables GPU/DCP-generated temporal dithering (FRC) on Apple silicon Macs (M1/M2/M3). It aims to reduce eyestrain and related symptoms for users sensitive to display flicker, with minimal image quality degradation.

## Use cases
- disable temporal dithering on Apple silicon Mac
- reduce eye strain from display flicker
- turn off FRC dithering on M1 M2 M3
- menu bar app to control GPU dithering
- make screen flicker-free on MacBook
- verify dithering is disabled via ioreg

## When to choose
- you are sensitive to PWM or temporal dithering and use an Apple silicon Mac
- you want a simple user-space toggle without kernel extensions
- you want dithering disabled automatically at login

## When to avoid
- you use an Intel Mac or macOS older than 13
- you need to control TCON-level dithering on the display panel itself
- you require color-critical work where any dithering-related banding is unacceptable
