We don’t need a big blob of blue in our peripheral while working. Gray is standard in interface design for a reason.

Yes

#adminmenu, #adminmenu .wp-submenu, #adminmenuback, #adminmenuwrap {
background-color: #23282d;
}

Not very minor if it immediately jumped out at me.

Why would the majority of people that spend a lot time in the WP backend likely want a blueish gray over gray? It’s hard to imagine.
