I cannot reproduce. You need to be sure you have enabled the Vertex Mode. Tint and Hue modifiers use Vertex Colors.

Thanks for response @antoniov, are you on windows?
@PratikPB2123 you confirmed the issue, can you double check?
I tried this on two machines, win 11 and win 10, reproduced every time in 3.0 and 3.1, here is my video:

@antoniov I narrowed the problem down to issue only appearing when you have instanced copies.

So it works as expeced when you have the geometry assigned only to one object (single user).

This is a problem when you want to do for example a crowd of people and only want to change t-shirt colors on them using tint modifer.

I was looking the same...it's related to instances...@frogstomp-4 could you test if the problem is the same in other modifiers? (all modifiers use the same function).

I can also reproduce. Richard confirmed your reported issue, not me :)

Worked: never

This particular case of multiple instances works as expected on 2.83.17

Now we can reconfirm this, no? (With little edit in task description)

I can see the problem is related to the stored pointers of material.

Ob: tinted->000001B689C36D78(Stroke)  Modif: 000001B689C370D8(Stroke)
Ob: hues->000001B689C37798(Material.001)  Modif: 000001B689C370D8(Stroke)
Ob: hues->000001B689C36D78(Stroke)  Modif: 000001B689C370D8(Stroke)```

The object shared the same pointer, but in the modifier, the stored pointer is different.

@PratikPB2123:
So far I can confirm the same issue for:

Opacity
Tint
Hue

I'll update the comment if I discover more
Update: issue seems to only affect those modifier working with vertex colors listed above
