Simulate Color Space

[jmsim...@gmail.com]

Hi,

Apologies for the quick fire posts today.  Just started using the application and finding it really useful.

Is it possible to get/set the Simulate Color Space option normally found in the Developer Options screen?  Ideally looking to put this in a flow that switches to monochromacy when a time of day is reached so that the screen is easier on the eyes.

Unlikely, i can't find any hidden settings for it:

Thanks for looking Henrik.  I thought I was going mad searching through all the blocks thinking that I was typing in the wrong search term.

I guess that flow will have to go on hold for a while.

And what about?

ACCESSIBILITY_DISPLAY_DALTONIZER_ENABLED

[Henrik "The Developer" Lindqvist]

Yes, that may be it.

To enable/disable use the System setting set block with category Secure, name "accessibility_display_daltonizer_enabled" and value 1 for on or 0 for off.
To change colors use category Secure, name "accessibility_display_daltonizer" and value 0 for simulate monochromacy or 12 for correct deuteranomaly:

Thanks. Looks like that'll need me to root the device is that right? This one isn't currently rooted.

Oh well, thanks for your help.

Modifying settings in the Global or Secure category requires a rooted device.

Henrik,

Setting system property worked for me.

Thanks a lot for clarifying this.

The option to simulate colour space is for developers to understand how their their app might look to a colour blind user.
