The r field of the Color struct represents the red component of a color. It is a float value that typically ranges from 0 to 1, where 0 indicates no red and 1 indicates full red. 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 is useful when you need to adjust the red intensity of a color or when you are constructing a color programmatically.
// Example of accessing and modifying the red component of a Color Color myColor = new Color(); myColor.r = 0.5f; // Set the red component to 50% // Accessing the red component float redValue = myColor.r; // Example of exceeding the typical range myColor.r = 1.5f; // Set the red component to 150% for HDR
