Setting own TextArea style doesn't work (base_style doesn't have a color attribute)

[mistotebe]

The bug

Trying to use a TextAreaTheme with a base_style doesn't seem to work, TextArea._set_theme() seems to expect that a Style object has a color attribute which isn't the case.

Either it should be a RichStyle or maybe it wants to use base_style.foreground?

from textual.app import App, ComposeResult
from textual.style import Style
from textual.widgets import TextArea
from textual.widgets.text_area import TextAreaTheme

class MyTextArea(TextArea):
    MY_THEME = TextAreaTheme(name="mytheme", base_style=Style("white", "default"))

    def on_mount(self) -> None:
        self.register_theme(self.MY_THEME)
        self.theme = "mytheme"

class MyTUI(App):
    def compose(self) -> ComposeResult:
        yield MyTextArea()

if __name__ == "__main__":
    MyTUI().run()

->

.../tester.py:11 in on_mount
AttributeError: 'Style' object has no attribute 'color'

It takes a Rich Style. If you enable type checking in your IDE it should warn you about these kind of issues.

Right, my bad, I should have checked the module's imports. Sorry for the noise.
