Am i missing why you can't just say the color of hat that you see in front of you?

I came up with another plan. Let me name the prisoners p1 to p10, p1 being the tallest and p10 being the shortest. P1 obviously can’t guess his hat colour. So he just says the colour of p2. Now p2 knows his colour. The strategy is, if p3 has the same color as p2, p2 just immediately says the color of his hat. Since the answer was immediate p3 knows that he’s wearing the same colour. But if p2 sees that p3 is wearing a different colour, he says his hat color after a long pause of 5 minutes. The pause meant that p2 and p3 aren’t wearing the same colour. So simple terms,
P1 tells the color of p2
P2 now knows his colour
If p3 is the same colour, he immediately says his colour
If not, he takes a long pause of 5 minutes before he says his own color
By paying attention to the timing p3 knows if his hat color is the same as p2’s

The first person can just simply tell the next person hat color. This way the first person has a 50% chance but the next guy directly knows the color of their hat.

I think my idea doesn't break the rules: thd first one says the color of the next hat. Then the others will either say their color immediately or after a pause, depending on whether the next hat is the same color or not.

I came up with idea that each person says hat color of the person standing in front of him. So probability of the first guess is 50% and everybody else will be correct for sure. This plan is much easier to follow and to be understood correctly

Can anyone guess what the flaw in my logic was (as i explain it).
I figured.. the original person could just call out the color of the person in front of him, then everyone else follow the same rule.. as a way to communicate.

Or just.. agree beforehand to say the hat colour of the person in front of you.
Only the last guy will be wrong but everyone else will win.
Or, is the keyword "guess"?

If everyone says the color of the hat in front of them, the last person would have a 50% chance of guessing the first person’s hat. Regardless if the last person gets it correct, it’s still 9 of 10 correct right??

In the rules there are nothing stating that you can or cannot take your own hat off. So everyone takes their hat of and looks at it :)
