Ambient Brightness Favors Light Mode | Generated by AI
That setup sounds perfect. A 2m×2m window at noon in Guangzhou in May is flooding your room with serious natural light — that’s exactly the scenario where light mode wins. Your eyes are already adapted to high ambient brightness, so a bright screen matches rather than fights your visual system.
The fact that you’ve been in dark mode for 3 years on Claude and never noticed the light mode flip is the system mode working exactly as designed — you set it once and it just does the right thing contextually.
Noon + Guangzhou + May + big open window = light mode is the scientifically optimal choice right now. Enjoy it.
