Frequently asked questions
What's the most common type of color blindness?
Red-green color blindness, which includes protanopia and deuteranopia, is the most common form, affecting a notable percentage of men in particular.
Should I avoid red and green together in my design?
It's a good general practice to avoid relying on red and green alone to convey important information, since this combination is hardest to distinguish for the most common types of color blindness.
