When the Kansas City Chiefs and Philadelphia Eagles square off on Sunday, it'll mark the fourth straight season in which the colors of the Super Bowl logo happen to match at least one of the teams playing.

The NFL brought some color and creativity back to the Super Bowl logo after a decade of repetitive designs. Here's a look back at some of the design changes.

The Super Bowl logo conspiracy theory proposes that the colors in the logo predict which teams will play against each other in the championship NFL playoff game and that the NFL controls the outcome. Theorists suggest the NFL is scripted for revenue purposes.

More recently, fans have pointed to the marketing the NFL uses for the Super Bowl. For years, individual logos have been created for each Super Bowl, well before it’s clear which teams will appear in the final game of the season.

The upcoming Chiefs-Eagles Super Bowl has added fuel to the fire of a popular NFL conspiracy involving the colors in the logo.

For the first two years of the new generation of Super Bowl logos, the colors on the logo have lined up with the game’s eventual matchup — Bengals vs. Rams and then Chiefs vs. Eagles. That streak only ended last season when the Ravens lost to the Chiefs in AFC title game, but we came awfully close to three in a row.
