what difference between (+) marked and blue color on the (+) marked
(+)marked represents the point of amplitude in the constellation diagram
blue color on the plus sign (the others around them.) represents noise
I think the reason

The reason is due to the presence of noise in the channel. Where signs represent + the exact locations of pairs of amplitude, while other marks represent sites of noisy data

This explanation is in the link
