Things that are yellow and black

Yellow and black is the highest-contrast colour pair there is, so animals use it to say “don’t eat me” and people use it for hazards, taxis and diggers. The list below is sorted by type.

Jev, the AI judge that scores Overlaple, says whether it fits both.

55 examples, by type

Every answer was checked by hand and scored by Jev, TypeSafe’s AI judge, on Wednesday, 4 November 2026, with the same questions it asks for an Overlaple square. Where Jev is at least 50% sure of both sides, from the name alone, the two numbers are shown: 26 of 55 answers reach that, enough to fit a game square. The rest are true and stay listed without a score, because from the name alone Jev is less sure of one side.

Questions people ask

Why are so many animals yellow and black?

It is warning colouration: wasps sting, fire salamanders are toxic, and predators learn to avoid the pattern. Some harmless animals, like hoverflies, copy it to be left alone.

Why are warning signs yellow and black?

The pair gives the strongest contrast of any two colours, so it is readable from a distance and in bad light. The international standard for safety signs (ISO 3864) uses a black symbol on yellow for warnings.

Which sports teams are yellow and black?

Pittsburgh’s Steelers, Pirates and Penguins (black and gold), the Boston Bruins, Borussia Dortmund, Peñarol and Watford, among others.
