Have you ever worked with ApplicationBar icons in Windows Phone?
I have, I’ve been working on Imnuri Crestine a Hymnal app you can see my first post about it here (Article is in Romanian)
While working on it I had to add some ApplicationBar icons to by AppBar and I had to create my own icons.
First thing I was worrying about was how do I make it Light Brown?
At first I was making my icons in PNG format using the color I needed in the result, as soon as I changed the default color I had to remake all the ApplicationBar icons until by mistake I tried a white icon and it took the default theme color.
So when you want to set a custom theme to your ApplicationBar just create white/transparent icons and the white will be replaced with the color of the ApplicationBar.
