This theme series is a continuation of the Classic-Colors theme and icon series. This theme series is now based on the Marwaita themes (special thanks to DarkoMarko42 for uploading those!), redone to my personal tastes, in 25 different colors, each with 4 light/dark variants, as illustrated in the scrolling preview screenshots (all of these themes have dark panels). These themes also include corresponding Mutter, Metacity, Xfwm, and Openbox themes.
The reason I changed the theme base for these themes is because of two issues I had with the previous themes:
1) Seemingly random success, warning, and error colors. These themes provide consistent success, warning, and error colors.
2) The text in highlighted items in Xfce displayed the text_color where they should have displayed the selected_fg_color. Here, they show up properly in Xfce.
