It’s a mystery for now.
Since the launch of Pokemon GO, players have discovered a handful of cool Easter eggs in the game. For instance, naming your Eevee a certain name will allow you to control the evolution form you get, and walking away from your Pokemon starters a certain number of times at the beginning of the game will cause a Pikachu to spawn.
It looks like Reddit user BroDallas might have just unearthed a new Easter egg. However, no one seems to be able to figure out exactly what it means. Here’s how it goes:
When you have the Pokemon GO app open, tapping the Poke Ball icon at the bottom of your screen will bring you to your menu. Tapping any of the icons (Pokedex, Pokemon, Items, Shop) will cause them to glow a faint greenish-blue before taking you to the next menu screen. No issue there.
However, if you press and hold the Poke Ball icon at the bottom of the screen to go to the menu, tapping the various icons will cause them to glow a different color, and you won’t be taken to the corresponding menu screens. For example, press and hold the Poke Ball icon on your app, and while you’re still holding down that portion of your screen, you can tap the Pokemon icon and you’ll see an orange glow. But nothing else happens.
The Pokedex icon gives off a reddish glow, while the Shop and Items icons give off slightly different shades of purple.
No one seems to know what this means, but players believe that there must be some sort of color combination here that will activate something. Who knows? It might just trigger the appearance of a rare or legendary Pokemon.
