The warmest light a screen can make
Candlelight sits around 1,800–1,900K, warmer than any household bulb. The page keeps almost every pixel dark and lights only a small flame and the glow around it, so the light that reaches the room is low, warm and carries very little blue — closer to a candle than a dimmed white screen can manage.
Gazing at a candle flame is an old concentration practice, sometimes called trataka.

No wax, no smoke, nothing to blow out
A screen candle is safe to leave burning in a child's room, beside a bed or on a crowded table, and it turns itself off with the sleep timer.
