Is it possible to add dynamic colors to a TextBlock ..i.e. have one character in one color and the next in another color.
Actually, you can, which can come in handy when you're doing a StringFormat on a data bound Textblock or a number of other places.
If you did want to try it though, like here's an SL example for a form label that puts a red asterisk next to the text Required Fields, but then can also add more stuff to it as shown in the example. Should work for Silverlight, WPF, UWP, etc...
