From the Start screen of the phone or phone emulator, click or touch the right arrow at the upper right and navigate to the Settings page and then select Theme. A Windows Phone 7 theme consists of a Background and an Accent
color. For the Background you can select either Dark (light text on a
dark background, which you’ve been seeing) or Light (the opposite).
Select the Light theme, run SilverlightHelloPhone again, and express
some satisfaction that the theme colors are automatically applied:
Although these
colors are applied automatically, you’re not stuck with them in your
application. If you’d like the text to be displayed in a different color, you can try setting the Foreground attribute in the TextBlock tag, for example:
Foreground="Red"
You can put it anywhere in the
tag as long as you leave spaces on either side. As you type this
attribute, you’ll see a list of colors pop up. Silverlight supports the
140 color names supported by many browsers, as well as a bonus 141st color, Transparent.
In a real-world program,
you’ll want to test out any custom colors with the available themes so
text doesn’t mysteriously disappear or becomes hard to read.
