How can you implement this dynamic color effect ?

 <Rectangle Grid.RowSpan="3">
                                <Rectangle.Fill>
                                    <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
                                        <GradientStop Offset="0" Color="#00000000" />
                                        <GradientStop Offset="1" Color="{x:Bind local:UIHelper.ToColour(ColourHex), Mode=OneWay}" />
                                    </LinearGradientBrush>
                                </Rectangle.Fill>
                            </Rectangle>

I see that you use the UIHelper, but I don't see where the ColourHex comes from. Is the ColourHex the color that is extracted by the binding Image?

The colour hex is pre-computed and stored in ambie's server. It's not calculated on the fly.
