I’m a product designer and I totally bombed this. Never in my career have I been required to know exact hex codes (especially of pure blue - which I have never used thankfully), or exact border radii.<p>This quiz misses the idea that humans perceive the same values differently in different contexts. A button with 5px border radius might not feel “round” enough in a UI where everything else is very “round”. Or if you have two colours of the same hex value, except that one is surrounded by white pixels, and the other is surrounded by black ones, then it is unlikely that the colour will be perceived the same way in both cases (see the Checkerboard illusion). Identifying fonts immediately by just looking at them (which I can do well) has been a neat party trick, but has never found utility in my work.<p>A designer’s strength is not knowing these values by rote, but having the sensitivity to understand the tools at our disposal (including knowing how human perception works) and using them to create something functional and beautiful.<p>This “test” does not evaluate any of that.
