For a Column chart (grColumn constant), this parameter corresponds to the category subscript: all the bars of the category will be colored. The colors specified for the category series will be ignored.
For a Bubble chart (grBubbleChart constant), this parameter corresponds to the category subscript: the bubble corresponding to the category will be colored.

<Color>: Integer or Integer constant

Color of specified category. This color can correspond to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a preset color.

Remarks

The colors defined by <Chart>.CategoryColor will be taken into account during the next call to <Chart>.Draw.
To display the color gradients, use <Chart>.Gradient.
The colors specified by <Chart>.CategoryColor are taken into account in the Waterfall charts. You also have the ability to define the colors of categories in the Waterfall charts with <Chart>.WaterfallColor.
