Mayo vs. Ketchup (2017)

Mayo vs. Ketchup was a worldwide Splatfest event in Splatoon 2. It was announced on 2017-07-29. Results were segregated for each region. The results were given on 2017-08-06.

Details
The Splatfest theme was the two condiments, mayonnaise and ketchup.

Mayo vs. Ketchup featured the first Shifty Station layout, "Push".

If the Mayo vs. Ketchup Splatfest had combined results instead of segregated, Team Ketchup would have been declared the winner, taking both the popular vote (due to Team Ketchup's greater popularity in the west) and team play (due to Japan outplaying the other two regions combined in that category by a factor of roughly 8.7 to 1).
 * Popularity: Mayo 679318 - Ketchup 830583
 * Solo play: Mayo 1529074 - Ketchup 1480605
 * Team play: Mayo 72695 - Ketchup 75073

The colors white/cream and red were used in Mayo vs. Ketchup. This is the first time that these colors have been used internationally in the entire Splatoon series; the Japanese Lemon Tea vs. Milk Tea featured white/tan ink for Milk Tea and the European Barbarian vs. Ninja featured red ink for Barbarian.
