Cannot use colors on winforms

Expected Behavior

Using the packer color attribute to change the color of a Label.

Current Behavior

No color displayed, no errors, widget still gets displayed.

Your Environment

import toga
from toga.style import Pack
from toga.style.pack import COLUMN, ROW

class AppName(toga.App):
    def startup(self):
        main_box = toga.Box(style=Pack(direction=COLUMN))

        self.id_error = toga.Label(
            'Error',
            style=Pack(visibility='hidden', text_align='center')
        )
        error_box = toga.Box(style=Pack(direction=COLUMN, padding=5))
        error_box.add(self.id_error)

        main_box.add(error_box)
        self.main_window = toga.MainWindow(title=self.formal_name)
        self.main_window.content = main_box
        self.main_window.show()

Thanks for the report! There’s a lot of features on the winforms backend that aren’t currently supported - changing colors is one of them. However, this isn’t reported in the same way as it is with other missing features, so the confusion is understandable.

(And - for future reference: you’re using the winforms backend. We’re in the process of deprecating the win32 backend).
