Since allot of people aren't happy with the Plata theme i thought i might suggest an theme that i found on Gnome-Look.org.
This theme is called "Sweet" and it comes in many colors, the reason i wanna suggest this theme is because it has almost the same colors as the terminal does so in my opinion this can be a good fit for Solus.

Let me know what you guys think about it.
