What does the blue numbers mean on players profile?

Is it indicating that's the highest it can go? It can't go any higher even if the potential has not been reached?

On attributes? Different number ranges (from the range 1-20) have different colours to broadly seperate them into weak and strong attributes. It isn't anything to do with potential.

Yeah the attribute numbers. What does the blue ones mean? Just means that's their strong attributes? Not like that's the highest it will go for that attribute?

It simply means attributes they are very good in.

16+ is dark blue. It's just so you can glance at it and see "oh, he's dark blue in X, Y and Z, he's a good player."

I have someone who is blue at 11. It's not 16+ that is catered a colour is it?

There are different shades of blue. I can't tell you all of the different values for each different shade. SCIAG might be able to.

Who do you think I am?

Like canvey says, there are different shades of blue. Dark blue is what I'm talking about. I think 1-5 is one colour, then 6-10, then 11-15. I may be wrong, however. It's just banding them, nothing else.
