The world stays the same. Your perception does not.
Colorblind Swap is a lightweight full-screen post-processing shader that alters how colors are perceived over time. Instead of applying a fixed color filter, the shader periodically changes the relationship between color channels, causing different parts of the spectrum to be interpreted in new ways. The result is a shifting visual experience where familiar environments can temporarily appear as though viewed through different forms of altered color perception.
✨ Highlights
Dynamic Color Perception Shifts.
The shader operates in timed intervals and selects a new color interpretation mode for each cycle. Rather than permanently remapping colors, it continuously transitions between different channel configurations, making the visual effect feel unstable and perceptual rather than purely cosmetic.
Red–Green Channel Reassignment.
One of the available modes exchanges portions of the red and green channels. Reds begin to inherit green information and vice versa, creating a perception similar to common red–green color vision deficiencies while preserving overall scene brightness.
Blue–Green Spectral Blending.
Another mode blends blue and green information together. Vegetation, water, sky colors, and other blue-green surfaces gradually lose their usual separation, producing a shifted color balance across the scene.
