Real-time Image Correction for Colorblind Users

• Most games with a “colorblind mode” swap hard assets – meshes, textures, etc.
• Image correction for colorblind users already exists for still photographs and images
• Combine the two: make a post-process effect that acts as a real-time color filter – goal is minimal framerate loss
• Demonstration made using C++ with the DirectX 11 API and HLSL shader code
• Transforms made between several color spaces: RGB, LMS, CIE xyY, CIE L*a*b
• Planned total development and testing time of 16 weeks
• Development finished! Results and paper are available here.

Types of colorblindness and how they impair gameplay – only three distinguishable colors instead of four. Compare with the corrected versions below.
