The system-wide menu quickly converts your art into a palette that simulates what colorblind people see. Color Oracle integrates smoothly in your workflow. Select the type of color-blindness in the menu or press one of the keyboard shortcuts while you are working with your preferred graphics software. Color Oracle immediately filters your screen image and hides itself automatically when you press any key or click the mouse button.

Forms of Color Vision Impairment

Color Oracle simulates deuteranopia, protanopia and tritanopia. These are extreme forms of color blindness; most color deficient viewers are seeing more colors. Therefore, if you design your art for people with extreme color blindness, it will also be easily readable by those with minor color blindness and "normal" vision.

The number of people affected by color deficient vision is difficult to measure. Depending on the literature, one can find percentages between 1% and 12%. What is certain, however, is that color vision deficiency almost exclusively affects males. Color Oracle uses the following numbers:

  • Deuteranopia or deuteranomoly: 5% of all males.
  • Protanopia or protanomaly: 2.5% of all males.
  • Tritanopia: Less than 0.3% of women and men.

Note

Color Oracle is using the best available algorithm for simulating color vision impairment. However, highly saturated color may not simulate well using the present version of Color Oracle.
