Enable or Disable Reading Mode auf OnePlus
OnePlus phones include Reading mode to cut blue light and cooler tones, replacing them with warmer colors that reduce eye strain during long reading sessions or nighttime use. The system applies this as a display filter on top of whatever theme or wallpaper you use, so once enabled it affects the whole screen.
To adjust it, go to Open the Settings ➤ Tap on Display ➤ Tap on Reading mode ➤ Enable or disable Reading mode ➤ Choose Chromatic effect or Mono effect. Chromatic effect keeps some color visible while warming the tones, which works for browsing photos or watching video without losing all color information. Mono effect strips out most color, closer to an e-reader look, and suits long text-heavy sessions.
Reading mode is not the same as Dark mode or Night Light, since it changes color temperature rather than brightness or contrast. If your real problem is screen brightness at night rather than color, adjusting brightness or a dimmer schedule solves that faster. Photos, videos, and any color-sensitive work will look inaccurate while Reading mode is active, especially with Mono effect, so turn it off before editing images or watching content where color matters.
