Question

Using Java, how do I convert a human readable color name into a three-element integer array?

For example, I have a color represented by:

int[] RGB_COLOR = {128,25,25};

And I want to be able to convert the static value Color.BLUE into a three-element integer array that is similar to the one above. Is this possible or do I have to hack my way around this?

Do you mean like this…

Color c = Color.BLUE;
int[] RGB = { c.getRed(), c.getGreen(), c.getBlue() };

To convert a colour name to a Color you can use reflections, provided its own of the built in colours. If you want more colours you would need to use a map.

public static Color colorOf(String color) {
    try {
        return (Color) Color.class.getDeclaredField(color).get(null);
    } catch(Exception notAvailable) {
        return null; // ??
    }
}
