When you imagine what it's like to be colourblind, do you picture things as only being visible in black and white?
It turns out being colourblind is a lot more complex than that.
While some people with the condition can't see certain colours, others will see one colour swapped out for another, or a colour will appear more weak than others.
In a project highlighted by Refinery29, a series of gifs created by medical consulting company Clinic Compare show what it's really like for people who are colourblind.
