Adobe Cloud Tema Escuro

Hi there, 

Are you trying to change the theme in Acrobat?

The dark grey theme is already present in Acrobat, you can change the theme by following the below steps:

• Open the Adobe Acrobat DC app- Click on the View option.
• Navigate to Display Theme- Move your mouse pointer to the Display Theme option, under the Show/Hide text.
• Click on the Dark Gray option to enable the dark theme- Now your app's interface will turn to dark color.
• If you want to re-enable the light theme, just select Light Gray from the same option. Done!

Hope this helps!
