常见问题解答

How accurate is this simulation?
It uses widely-used color transformation matrices to approximate how each color vision deficiency perceives color. It is a helpful guide, not a clinical diagnostic tool.
What should I check for in the results?
Look for elements that rely only on color to convey meaning — like red/green status indicators — and check whether they remain distinguishable in each simulation.
Which type of color blindness is most common?
Deuteranopia (reduced green sensitivity) is the most common form, followed by protanopia (reduced red sensitivity). Both primarily affect men.
