It's very simple.

First, we need to discuss what Opposite Color is.

In general, Opposite Color means complementary color.

Wiki, Complementary Color

Please see the Wikipedia article for details.

In short, complementary colors are two colors that, when mixed, result in a perfect white color.

In RGB Color(0~255), white is (255, 255, 255).

For example, let's say you want to find the complementary color of blue. The RGB color of blue is (0, 0, 255) , so its complementary RGB value is (255, 255, 0), yellow.

Let's express what i've said so far in UnityScript.

Note: unity use normalized range.(as 0-1)

    private Color GetOppositeColor(Color color)
    {
        return new Color(1f - color.r, 1f - color.g, 1f - color.g);
    }
