Abstract
Real-time modification of pixel colors for displays, such as video game displays, may be performed to account for color vision deficiency. The modifications can be performed using operations utilizing constant matrices, with operations performed in the LMS color space. For example, a pixel may be transformed from an RGB color space to the LMS color space, a difference between a simulated color-vision deficient response and the pixel may be determined, and the difference may be distributed in the pixel such that the response is effectively taken from defective cones and distributed to functioning cones, with the resulting pixel transformed back to the RGB color space for display.
