RGBA stands for Red, Green, Blue, and Alpha. Computer graphics uses RGB to represent color in an image. Each color code of RGBA specifies that color channels of Red Green Blue and Alpha represent the transparency of opacity of the HEX color code.

Each component in RGBA is between 0 to 255 in 8 bits, 0 represents for lowest and 255 is the highest.

Red (R): It describes the red color intensity.

Green (G): It describes the Green color intensity.

Blue (B): It describes the Blue color intensity.

Alpha (A): It describes the transparency of color. A value of 0 means fully transparent, and 255 means fully shown.

The RGBA format is commonly used in different websites and web applications, to define colors with transparency. For example, For instance, RGBA(255, 255, 255, 1) represents the colour white at full opacity while RGBA(0, 0, 0, 0.5) represents the colour black at 50% transparency.

Hexadecimal color refers to the use of hexadecimal code to express color code. It uses a six-digit code to represent color where each pair of numbers stands in Red, Green, and Blue color channels.

A value between 00 and FF, where 00 is the lowest intensity and FF is the maximum, is represented by each pair of hexadecimal numbers. The construction of a hex color code is as follows: #RRGGBB.

Red color hex code #FF0000

Green color hex code #00FF00

Blue color hex code #0000FF

Black color hex code #000000

White color hex code #FFFFFF

The format for the eight-digit hex color code is #RRGGBBAA, and it has two extra digits for the alpha channel (transparency) in addition to the six-digit version.

Convert an RGBA color to a hex color code, you can follow these steps:

Convert RGB Values to Hex:

Take the Red, Green, and Blue components of the RGBA color. Convert each component from decimal to hexadecimal.Ensure that each hex value is a two-digit number.

Here's an example:

RGBA color: rgba(255, 127, 64, 0.5).

Convert RGB to Hex:

Red: 255 → FF

Green: 127 → 7F

Blue: 64 → 40

Convert Alpha to Hex:

Alpha: 0.5 → 0.5 * 255 = 128 → 80 in hex

Combine Values:

Hex color code: #FF7F4080

So, RGBA color is #FF7F4080.
