Can you make an item change the screen tone?

So, I've set it so when you get poisoned in battle, the screen tints green when you're in the overworld.

I want to be able to make it so if you take an antidote item in the overworld, the screen will return to its normal colour.

Is this possible or do you need a plugin?

I think you can make it add a common event that will tint the screen in the poison state on database.
And add another common event in the antidote item in database to tint the screen to normal.
