In many systems when there are more than 8 bits per channel (such as 16 bits or floating-point), the channels are stored in RGBA order, even if 8-bit channels are stored in some other order. On a little endian architecture this is equivalent to ABGR32.

In OpenGL and Portable Network Graphics (PNG), the RGBA byte order is used, where the colors are stored in memory such that R is at the lowest address, G after it, B after that, and A last.

This article will use a scheme that has some popularity, which is to add the suffix '8888' to indicate if 4 8-bit units or '32' if one 32-bit unit are being discussed. Therefore, to be unambiguous, it is important to state which ordering is used when referring to the encoding. This is not the case for a little-endian system, where the two mnemonics are reverses of each other. In a big-endian system, the two schemes are equivalent.

In the word-order scheme, 'RGBA' is understood to represent a complete 32-bit word, where R is more significant than G, which is more significant than B, which is more significant than A.This scheme is commonly used for describing file formats or network protocols, which are both byte-oriented. In the byte-order scheme, 'RGBA' is understood to mean a byte R, followed by a byte G, followed by a byte B, and followed by a byte A.There are two typical ways to understand a mnemonic such as 'RGBA': The interpretation of these 4-letter mnemonics is not well established. These encodings are often denoted by the four letters in some order (e.g. The order of these four bytes in memory can differ, which can lead to confusion when image data is exchanged. By far the most common format is to store 8 bits (one byte) for each channel, which is 32 bits for each pixel. In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha. You could avoid the rgba model altogether and use the transparent keyword instead, which according to w3.org, is equivalent to вЂњtransparent blackвЂќ and should compute to rgba(0, 0, 0, 0).In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). you will see an obvious problem if the alpha value changes to something undesirable.it keeps a few extra bytes out of your CSS file, and.

With that in mind, I would choose rgba(0, 0, 0, 0) because: If you set it to 0 it will mean вЂњcompletely transparentвЂќ, and the first three parameters (the red, green, and blue channels) wonвЂ™t matter because you wonвЂ™t be able to see the color anyway. The last parameter to the rgba() function is the вЂњalphaвЂќ or вЂњopacityвЂќ parameter. What are the pros and cons of each? Solution Should you use rgba(0, 0, 0, 0) or rgba(255, 255, 255, 0) for transparency in CSS?
