Renaming the theme you use either Ambiance Green, Ambiance Blue ect..... to Ambiance gets rid of the white corner issues. So in theory whatever theme you use name it Ambiance and the white corners are gone for me :)

thanks for the suggestions
could you send some screenshots would appreciate suggestions for a better view

Here is a combine screenshot, which also includes a Nautilus issue from the Ubuntu's default Ambiance theme:

Just A quick note on the nautilus "White Gap" issue. That is actually a bug in Ubuntu or Nautilus its self. EG you didn't break anything don't worry. I am still hunting for a fix/workaround my self. if anyone finds ones let me know

Eg: even if you copy the "actual" Ambiance theme from Ubuntu and rename it to Ambiance2 making no changes that issue appears. very annoying for users and theme makers :)

Thanks for these 4 Ambiance variants, which look very promising.
Here are my suggestions for future improvement:
1) Better naming, e.g. Ambiance colors; including Ambiance-Green, -Blue, etc.
2) I think the best is "Ambiance-02" (could be named Ambiance-Green) only two flaws: 1. GTK2 apps toolbar bgcolor does not exactly match the titlebar bgcolor although very close, 2. Synaptic Package manager toolbar bgcolor is light grey and consequently light icons there become hardly visible (although google chrome/chromium tabbar bgcolor matches the titlebar very nicely except the too light active tab bgcolor which makes light icons almost invisible)
3) All the same for "Ambiance-01" which apparently differs from "Ambiance-02" only in the selection color (orange vs green)
4) I think the variants named "Ambiance esmeralda" and "Ambiance variant" have a lot more to do, e.g. Unity Panel bgcolor not matching their titlebars, and a number of other areas also remaining dark grey.
5) I would love to see also a Blue variant along the lines of "Ambiance-02" probably with titlebar close button and others in a matching blue color as well.
