how to make a random generator in unity code example

Example 1: unity generate random color

//using Color
Color randomColor = new Color(
	Random.Range(0f, 1f), //Red
	Random.Range(0f, 1f), //Green
	Random.Range(0f, 1f), //Blue
	1, //Alpha (transparency)
);

//using Color32
Color32 randomColor = new Color32(
	Random.Range(0, 255), //Red
	Random.Range(0, 255), //Green
	Random.Range(0, 255), //Blue
	255, //Alpha (transparency)
);

Example 2: unity how to generate a random number

Vector3 position = new Vector3(Random.Range(-10.0f, 10.0f), 0, Random.Range(-10.0f, 10.0f));
