Why is my Evernote interface shades of gray and white

I use to use evernote on mac on a desktop on school campus sometime ago. 

I recently got got Evernote on mac ( not ios) and instead of green and white , I see shades of grey and white?  Boy I was sorely disappointed, I tried to see how I could change it but don't know how or if its possible for free users.   I think based on a color scheme I saw for options for upgrading Evernote, is the green and white just for users who pay for Evernote Premium use?

You are just seeing the latest UI. There are no options for free or premium users.

Green and white are the colours for the Webversion of Evernote and the apps for iOS and Android, I believe.

Terrible.

Evernote has a great UI in my opinion, it's just purely subpar (but a LOT) in the colors department.

The absence of a DARK MODE is so behind the times.  Being able to darken the sidebar is almost the opposite approach.

I want to darken the entire app.

I'm sure it's a limitation due to the fact that notes are basically HTML and they would have to re-engineer the app from the ground up.  Maybe I'm wrong.

Either way, I don't care because as a user I'm still entitled to complain
