0xARGB

0xARGB refers to a hexadecimal representation of color values that includes an alpha channel. The "0x" prefix is a common notation for hexadecimal numbers in programming. ARGB stands for Alpha, Red, Green, Blue, which are the four color components that define the color and its transparency. Each component is typically represented by two hexadecimal digits, ranging from 00 to FF, which corresponds to a decimal value from 0 to 255.

The Alpha channel determines the opacity of the color. A value of FF (255) means the color is fully opaque, while 00 (0) means it is completely transparent. The Red, Green, and Blue components specify the color itself, following the additive color model. For example, 0xFFFF0000 would represent a fully opaque red color, with the alpha component at its maximum, and the red component at its maximum, while green and blue are zero.

0xARGB is widely used in computer graphics, user interface design, and image processing. It allows for precise control over both the color and its transparency, enabling effects like gradients, blending, and semi-transparent overlays. Many programming languages and graphics libraries support this format for defining and manipulating colors. The order of the components (Alpha first) is a common convention in some systems, distinguishing it from other color formats like RGBA, which places the alpha channel at the end.
