Remarks

How to retrieve the components of the color?

To retrieve the components of the color returned by <Chart>.Color:

To get the red component, use RGBRed (or perform a division modulo 256 of <Result>),
To get the green component, use RGBGreen (or perform a division modulo 256 of <Result>/256),
To get the blue component, use RGBBlue (or perform a division modulo 256 of <Result>/256/256).

Colors of chart elements (legends, ...)

The setting performed by <Chart>.Color will be taken into account during the next call to <Chart>.Draw or during the next drawing of the chart (when resizing the host control, when modifying the popup menu, ...).
The transparent color can only be used for the background color of the legend (grColorLegendBackground constant).
Printing the chart: If the white color is associated with the axes (grColorAxis constant), with the gridlines (grColorGridlines constant), with the legend (grColorLegend constant) and with the border (grColorBorder constant), the drawing will be printed in black.
