Answer 1

You have to define Palette with same series name

            <BarSeries v-tkCartesianSeries :items="items1"
                categoryProperty="Country" valueProperty="Amount"
                seriesName="myLine" />
            <Palette v-tkCartesianPalette seriesName="myLine">
                <PaletteEntry v-tkCartesianPaletteEntry strokeWidth="5"
                    strokeColor="red" fillColor="red"></PaletteEntry>
            </Palette>
            <CategoricalAxis v-tkCartesianHorizontalAxis />
            <LinearAxis v-tkCartesianVerticalAxis />

Answer 2

Just use fillColor and strokeColor in the BarSeries

<RadCartesianChart>
   <CategoricalAxis v-tkCartesianHorizontalAxis />
   <LinearAxis v-tkCartesianVerticalAxis />
   <BarSeries v-tkCartesianSeries :items="items" categoryProperty="" valueProperty="" fillColor="red" />
</RadCartesianChart>
