Redshift - adjust screen color temperature

Redshift - adjust screen color temperature | Awesome Repos

Features

Ambient Lighting Synchronization - Matches the display brightness and color temperature to the surrounding environment using geographic location and solar position.
Color Temperature Managers - Adjusts the screen color temperature between warm and cold profiles to reduce eye strain based on the time of day.
Display Gamma Management - Modifies display output curves and individual color channels to fine-tune visual output and screen temperature.
Circadian Lighting Tools - Synchronizes display output with natural day-night cycles to support human circadian rhythms.
Geospatial Location Resolution - Provides mechanisms to resolve geographic coordinates from system providers to calibrate solar data for color adjustments.
Location-Aware Display Tools - Uses geographic coordinates to calculate the sun's position and automatically adjust display settings.
Gamma Ramps - Manipulates hardware-level gamma ramps to simulate precise brightness and color temperature shifts on the display.
Brightness Level Adjustments - Sets the display brightness level to match ambient lighting at different times of the day.
Temporal Brightness Scheduling - Automatically adjusts backlight levels to set distinct brightness profiles for day and night periods.
Display Profile Schedulers - Sets specific schedules or triggers to automatically shift screen colors and brightness at defined intervals.
Geographic Temperature Calculation - Computes the sun's elevation based on geographic coordinates and time to determine the ideal screen color temperature.
Temperature Interpolations - Gradually interpolates between day and night color temperature states over a set duration to ensure smooth visual transitions.
Time-Based Triggers - Triggers display profiles and color shifts based on user-defined clocks or predefined day-night cycles.
Location Services - Utilizes location services to determine coordinates for calculating solar positions and color adjustments.
Screen Color Fades - Gradually fades the screen color between day and night settings over a specified period.

Redshift is a circadian lighting tool and color temperature controller designed to align screen output with natural light cycles. It functions as a display manager for X11 environments, adjusting screen color temperature based on the time of day and geographic location to reduce eye strain. The software automates display lighting by calculating the sun's position using stored coordinates to shift screen colors from blue to warmer tones. It also acts as a screen brightness manager by manipulating gamma ramps to simulate precise brightness levels when hardware backlight controls are insufficien

Lunar is an adaptive monitor brightness controller and DDC/CI display manager. It allows for the control of hardware brightness, contrast, and volume on external monitors using native communication protocols. When direct hardware control is unavailable, it functions as a software gamma dimmer to simulate brightness reduction. The project synchronizes external monitor brightness with laptop light sensors, wireless lux meters, or astronomical sun position calculations. It also manages hardware monitor presets, enabling the automation of display configurations and input switching through custom
