The Chromatic Aberration toggle is an accessibility option added in Patch 1.04.00 under Settings > Accessibility. It controls whether the chromatic aberration filter is applied to the camera image. Turning it off removes the rainbow edge fringing on high-contrast UI and scene boundaries, which is helpful for players who find the effect distracting or who experience visual fatigue under the default look.
What It Does
Disables or reduces the rainbow edge tint that the post-process pipeline normally applies to high-contrast boundaries.
Helps players who find the default fringing distracting on UI text, especially the minimap and inventory tooltips.
Pairs naturally with the new Minimum Font Size setting from Patch 1.03.00; turning chromatic aberration off improves readability when font sizes are tightened.
How to Enable
Open Settings, navigate to Accessibility, and toggle Chromatic Aberration. The setting works independently of Colorblind Mode and Photosensitive Mode.
