0x00FF00

0x00FF00 is a hexadecimal constant commonly used in programming to represent a 24-bit RGB color value. In the RGB color model, it encodes red = 0, green = 255, blue = 0, which corresponds to pure green.

In the standard 24-bit color encoding, a color is written as 0xRRGGBB. For 0x00FF00, the red channel is 0x00, the green channel is 0xFF, and the blue channel is 0x00. The resulting numerical value is 65280 in decimal. Some programming environments also allow an alpha channel, but 0x00FF00 itself represents only the RGB components without transparency.

0x00FF00 differs from the CSS web color notation #00FF00 primarily in syntax. CSS uses a hash-prefixed hex triplet, while many programming languages use the 0x prefix for hexadecimal literals. Conceptually, they denote the same color, though the contexts and parsing rules differ.

Applications of 0x00FF00 include defining colors in graphics libraries, game development, UI toolkits, and image processing code. It is often used to designate green in user interfaces, highlight elements, or serve as a color constant in color comparisons and bitwise operations. Being a pure green value, it is also one of the primary colors in additive color systems, where green contributes to forming a broad range of perceived hues when combined with red and blue.
