Looks like a work in progress. Seems that someone is adding some new circuits - the hanging yellow romex. There's an open KO in the top of the panel, hopefully for those new ones.
It looks like there are neutrals and grounds mixed on the right bus; I can't see the bonding screw so I am not sure if this is a subpanel or not, but that lone ground coming in thru the conduit on the upper right implies that this is the main. The white reidentified with green as a ground looks a little to small to be restriped green.
Blues are OK for neutral (harmonized wiring uses blue for that) but having blue for both hot and neutral can be confusing.
