The r field represents the red component of a color in the Color struct. It is a floating-point value that typically ranges from 0 to 1, where 0 represents no red and 1 represents full red intensity. However, this value can exceed 1, allowing for high dynamic range (HDR) color representations.
To access or modify the red component of a Color instance, you can directly use the r field. This field is public and non-static, meaning it is accessed through an instance of the Color struct.
Color myColor = new Color(); myColor.r = 0.5f; // Set the red component to 50% intensity // Accessing the red component float redIntensity = myColor.r; // Example of exceeding the typical range myColor.r = 1.5f; // HDR value, exceeds the standard 0-1 range
