how to write an AppleScript to change the color profile ?

To any Service that you create in Automator, you can associate a keyboard shortcut.

Just go to System Preferences->Keyboard->Shortcuts, click on Services, locate the one you want, and add the shortcut.

This will get you more than half way:

1) In Automator, create a new "Quick Action" (aka "Service")

2) Add a single "Run Applescript" action, so that it looks like this:

3) Save the Quick Action with a descriptive name, like "Color Profile"

4) In System Preferences->Keyboard->Shortcuts->Services, add a convenient keyboard shortcut for this Service.

Now just by pressing one keyboard shortcut, you will be taken to the right place and can click on the desired profile

You could investigate further if you want to do this in a fully automatic way - making your Automator Service also "click" the correct profile; but I think this provides a **** good start.

Sorry, I don't understand Chinese.

My system is in English, and I have no experience with doing scripts like this in other languages.

I could try a little test in Portuguese (my native language), but only later, as this would involve restarting my mac and I have stuff running.

Maybe you have to replace "Displays" with the appropriate word in Chinese?

Is that really a bokd text or is my browser displaying wrong?

It is bold, alright. Phasers on stun.

I apologize. It was late and I was tired and I thought my Android phone was buggy.

I just did a quick test in Portuguese.

I had to use "Monitores" instead of "Displays" - that is, the name of the pane had to be written in Portuguese.

I suppose the same should happen in Chinese.

That's great to know.
