macOS 专用脚本

#!/bin/bash
# macOS 夜览定时脚本
# 语法: osa_scale 开始时间 结束时间 最终亮度
osascript -e '
on run argv
    set startHour to item 1 of argv as integer

        set brightnessValue to finalBrightness
    end if
    tell application "System Events"
        tell dock preferences
            set properties to {autohide:false}
        end tell
    end tell
    -- 这里可以设置夜览色温
    do shell script "echo 调整色温"
end run
'
# 主循环
while true; do
    HOUR=$(date +%H)
    if [ $HOUR -ge 6 ] && [ $HOUR -lt 18 ]; then
        # 白天 - 正常色温 6500K
        osascript -e 'set appearance to light'
    elif [ $HOUR -ge 18 ] && [ $HOUR -lt 22 ]; then
        # 傍晚 - 中间色温 4500K
        osascript -e 'set appearance to dark'
    else
        # 夜间 - 最低色温 3500K
        osascript -e 'set appearance to dark'
    fi
    sleep 300
done

配置文件示例

{
  "schedule": [
    {
      "start": "06:00",
      "end": "09:00",
      "temperature": 5500,
      "name": "早间"
    },
    {
      "start": "09:00",
      "end": "14:00",
      "temperature": 6500,
      "name": "正午"
    },
    {
      "start": "14:00",
      "end": "18:00",
      "temperature": 5800,
      "name": "午后"
    },
    {
      "start": "18:00",
      "end": "22:00",
      "temperature": 4500,
      "name": "晚间"
    },
    {
      "start": "22:00",
      "end": "06:00",
      "temperature": 3500,
      "name": "夜间"
    }
  ]
}

使用 systemd 服务（Linux）

# /etc/systemd/system/color-temperature.service
[Unit]
Description=Color Temperature Scheduler
After=network.target
[Service]
Type=simple
ExecStart=/usr/bin/python3 /home/user/color_temp_scheduler.py
Restart=on-failure
User=1000  # 改为你的 UID
[Install]
WantedBy=multi-user.target

使用方法

安装依赖：
- Linux: sudo apt install redshift
- Windows: 已自带夜灯功能
运行脚本：
```
python3 color_temp_scheduler.py
```

设置开机自启（Linux）：

sudo systemctl enable color-temperature
sudo systemctl start color-temperature

自定义时段：修改 config_file 中的 JSON 配置

注意事项

Linux 需要安装 redshift
Windows 夜灯功能需要 Windows 10/11
macOS 需要允许辅助功能权限
可以根据需要调整色温值和时段

这个脚本会根据一天中的不同时段自动调整屏幕色温，帮助保护眼睛并改善睡眠质量，需要调整具体时段或色温值时,只需修改配置文件即可。
