Colours In Column Chart

Question

Hi Team, I'm currently stuck at a point and would appreciate your input. I need to display different colors for different countries in a column chart. Below is the database structure I'm working with 
 country ListId(pK), 
 .countryId(int), 
 isAllowed(boolean) 
 
 Note: I want to show only allowed countries data in column chart. 
 I grouped the data by countryId, and I want to display different colors for different ranges of country IDs in a column chart. For example: Country IDs 1, 2, 3, and 4 should be shown in blue Country IDs 5, 6, 7, and 8 in yellow Country IDs 9 and 10 in another color These colors are just examples. If this approach is feasible, I will apply it to the actual requirement.

You can manage the colors by using multiple a!chartSeries() like below... 
 {
 a!columnChartField(
 label: "Column Chart",
 categories: {"Category 1", "Category 2", "Category 3"},
 series: {
 a!chartSeries(color: "#f0f0f0", label: "Country One", data: {1, 2, 3}),
 a!chartSeries(color: "ACCENT", label: "Country Two", data: {2, 3, 4}),
 },
 stacking: "NONE",
 showLegend: true,
 showTooltips: true,
 labelPosition: "ABOVE",
 allowImageDownload: true,
 colorScheme: "RAINFOREST",
 height: "MEDIUM",
 xAxisStyle: "STANDARD",
 yAxisStyle: "STANDARD"
 )
}
