I need help with my theme, please.

Could anyone please tell me how I can change (if it's possible at all) the background colors on the text messaging dialog (I'm creating my own theme).

I don't think it's possible. At most you can change the fonts of the text, and the color. Maybe event the text input space at the bottom of the screen, but that's about it.

All the options showing what is customizable can be found in Themebuilder. If it's not there, it can't be changed.

You may want to check in "Theme Global Items" in theme builder. It will be application color.
