Problem with a colored icon in colorful themes

Hi Patrick,

In a Colorful theme where the title bar has an intense colored background, normal button icons in the title bar won't show up properly since the contrast would be very poor with the background.  That's why Office apps make the icons white monochrome when in the title bar (and when the QAT is in the title bar), so that there is proper contrast and they are distinguishable.

Can you describe more about your scenario, and why you might not want this important accessbility behavior?

Hi, 

we would like to show our colored icon if the undo will affect something that isn´t currenty open. 
Is there some kind of way to get it to show the colored icon regardless of the selected theme?

Hi Patrick,

Our ribbon button templates set the DynamicImage control's UseMonochrome property to true if the attached ribbon:RibbonControlService.UseMonochromeImage property on the containing button control is true.  There are triggers that kick all that in.  The reason the property is on the control instead of the image source is most of the time, the theme and containing control (e.g. button) location determine its value.

Here's an example of overriding it:

<ribbon:Ribbon.QuickAccessToolBarItems>
	<ribbon:Button Id="Save" Command="ApplicationCommands.Save" ribbon:RibbonControlService.UseMonochromeImage="False" />
</ribbon:Ribbon.QuickAccessToolBarItems>
