The official logo of the PBA 37th season has been released. As you can see the color orange is the dominant color in the logo. Well, the color orange represents the color of the earth in Indian Philosophy.
The PBA probably wants to advocate Earth preservation that's why they chose the color orange.
Apparently, the NBA also did something like that. They also changed their logo to adapt into the Green Week Revolution. They called their logo the "NBA Green Week Logo."
The NBA participated in the Green Week because they want to remind their players as well as their fans to be always environmentally responsible citizens. It had a great impact on their players. In fact, it prompted some of their players to use their manually powered bikes instead of their cars. Hopefully, the PBA can also influence their players to do the same thing.
