Start with a neutral picture preset and reduce excessive colour or saturation processing while watching familiar faces and natural objects. A vivid logo is a poor reference because its intended colour may already be strong. Signal-format mismatches and source grading should also be considered before making global corrections.
Separate strength from accuracy
Increasing saturation makes colours more intense, but does not add colour detail or establish a wider-gamut source. It can make grass fluorescent and skin unnaturally orange. A wide colour-space option can also be unsuitable if it ignores how the source should be mapped, so use documented automatic handling where appropriate.
Compare several scenes
Use daylight faces, a studio interview and a subdued film passage. A single stylised scene may be intentionally unusual. Keep the same brightness and contrast while adjusting colour, and inspect red clothing or signs for lost texture. Extreme settings can merge distinct shades into a flat patch.
Check each active mode
HDR and SDR, built-in apps and HDMI inputs may remember different presets. If only one path looks oversaturated, inspect that path before changing the whole television. Report a persistent source-specific problem with its title and time. Do not promise that a multicolour website theme reflects the actual colour accuracy of every available stream.
