However, there are a few ways to get a similar effect:
1. Use a Third-Party App:
* Grayscale filters: Some third-party apps can overlay a grayscale filter on your phone screen, which will make Pokemon GO appear black and white.
* Night Mode: Many phones have built-in night mode features that change the color scheme of the screen to a darker, more muted palette. This can help to reduce eye strain and make the game look less colorful.
2. Use a Phone Setting:
* Colorblind mode: Some phones have a built-in colorblind mode setting that can help make the game look more monochrome.
Important Note:
* Be aware that using third-party apps can be risky, as they might access your personal data or interfere with your phone's functions.
* Always download apps from trusted sources and be cautious before granting them access to your phone.
Alternatives:
* Play during the night: Since Pokemon GO uses real-world lighting, you can play at night to get a more muted and darker experience.
* Choose Pokemon with black and white color schemes: There are many Pokemon that are already predominantly black and white, like Zoroark, Arceus, and others.
Remember, these are just workarounds and don't provide the exact functionality of a built-in "sleep mode" or a black and white filter in Pokemon GO.
