Wellness Wednesday for March 20, 2024

The Wednesday Wellness threads are meant to encourage users to ask for and provide advice and motivation to improve their lives. It isn't intended as a 'containment thread' and any content which could go here could instead be posted in its own thread. You could post:

  • Requests for advice and / or encouragement. On basically any topic and for any scale of problem.

  • Updates to let us know how you are doing. This provides valuable feedback on past advice / encouragement and will hopefully make people feel a little more motivated to follow through. If you want to be reminded to post your update, see the post titled 'update reminders', below.

  • Advice. This can be in response to a request for advice or just something that you think could be generally useful for many people here.

  • Encouragement. Probably best directed at specific users, but if you feel like just encouraging people in general I don't think anyone is going to object. I don't think I really need to say this, but just to be clear; encouragement should have a generally positive tone and not shame people (if people feel that shame might be an effective tool for motivating people, please discuss this so we can form a group consensus on how to use it rather than just trying it).

adb shell settings put secure accessibility_display_daltonizer -1 I believe should do it. That's from ChatGPT, so grain of salt, but, it looks plausible and similar to these github colorblindness tricks. Also not clear to me if you can override that from settings without adb, which would defeat the purpose, but I say give it a try. See also google groups.

Claude Opus agrees, but suggests using Tasker to toggle it instead:

Yes, the ADB command you mentioned:

adb shell settings put secure accessibility_display_daltonizer -1

This command sets the accessibility_display_daltonizer setting in the "secure" settings database to -1, which corresponds to the "Grayscale" color correction mode.

This command will enable grayscale mode on your device. However, there are a few things to keep in mind:

  1. This setting can still be changed by the user through the Accessibility settings on the device. So while it's a little more hidden than the quick settings toggle, it's not completely permanent.

  2. When you reboot your device, the setting might revert back to the default value (depending on your device and Android version). You may need to re-run the ADB command after each reboot to re-enable grayscale mode.

  3. Some apps or system processes might override this setting temporarily for specific screens or UI elements.

So while this ADB command is a good way to enable grayscale mode in a slightly more persistent way than the standard user-facing settings, it's not 100% permanent and unalterable.

If you want to make it a bit more automated, you could set up a Tasker profile or use a similar automation app to run this ADB command on device boot or periodically to keep re-enforcing the grayscale setting. Let me know if you have any other questions!
