Turn On/Off Color Correction auf Samsung
Color correction sits inside the visibility tools built for users with red-green or blue-yellow color vision deficiencies, known as Deuteranomaly, Protanomaly and Tritanomaly. Once enabled, the system applies a color filter across the entire interface, not just single apps, so icons, photos and menus shift toward tones that are easier to distinguish.
You reach the toggle through Tap on Settings ➕ Tap on Accessibility ➕ Tap on Visibility enhancements ➕ Tap on Color correction ➕ Enable or disable Use Color correction ➕ Choose an option. The last step lets you pick the correction type that matches your color vision, since each one shifts a different part of the spectrum.
If your screen looks fine to you but photos seem dull or overly warm, the cause is more likely a display mode or color balance setting, not this accessibility filter. Turning on the wrong correction type can make colors look unnatural for someone without a color vision deficiency, so only enable it if you actually notice trouble telling colors apart.
The filter applies system-wide and stays active until you disable it or switch the option back, so check this setting first if colors suddenly look off after a factory reset or software update.
