Did you find any workaround?

Setting the FontImageSource Colour works but then it would need updating on selection to have selected and unselected different colours

I think this is a duplicate of #12250 and there's a workaround for this issue on #12250 (comment)

[ReamsIT-Darren]

The workaround on #12250 does not seem to work when using Tabs on a Flyout on shell.

This issue seems to be fixed - tested on iOS with 8.0.20-nightly.10316 and the following code:

<Shell.Resources>
		<ResourceDictionary>
			<Style x:Key="BaseStyle" TargetType="Element">
				<Setter Property="Shell.BackgroundColor" Value="{StaticResource PrimaryColor}" />
				<Setter Property="Shell.ForegroundColor" Value="Yellow" />
				<Setter Property="Shell.TitleColor" Value="Black" />
				<Setter Property="Shell.DisabledColor" Value="Pink" />
				<Setter Property="Shell.UnselectedColor" Value="Purple" />
				<Setter Property="Shell.TabBarBackgroundColor" Value="{StaticResource PrimaryColor}" />
				<Setter Property="Shell.TabBarForegroundColor" Value="Blue"/>
				<Setter Property="Shell.TabBarUnselectedColor" Value="Green"/>
				<Setter Property="Shell.TabBarTitleColor" Value="Red"/>
			</Style>
		</ResourceDictionary>
	</Shell.Resources>
	
	<TabBar>
		<ShellContent Title="About" ContentTemplate="{DataTemplate local:MainPage}">
			<ShellContent.Icon>
                <FontImageSource FontFamily="FA" 
                                 Glyph="&#xe922;"
				 Color="Blue"
                                 Size="25"/>
            </ShellContent.Icon>

		</ShellContent>
		<ShellContent Title="Items"  ContentTemplate="{DataTemplate local:MainPage}">
			<ShellContent.Icon>
                <FontImageSource FontFamily="FA"
				 Color="red"
                                 Glyph="&#xe922;" 
                                 Size="25"/>
            </ShellContent.Icon>
		</ShellContent>
	</TabBar>
