RGBA

Red Green Blue Alpha

In the RGBA color model, colors are represented by specifying the intensity of the primary colors red, green, and blue, as well as an alpha value that specifies the transparency of the color.

The RGBA color model is similar to the RGB color model, but it includes an additional alpha value that specifies the transparency of the color. The alpha value is a decimal number between 0 and 1, where 0 is fully transparent and 1 is fully opaque.

In HTML and CSS, RGBA colors are specified using the rgba() function, which takes four values: three values between 0 and 255 that represent the intensity of the primary colors (red, green, and blue), and a fourth value between 0 and 1 that represents the alpha value. For example, the color white with 50% transparency is represented as rgba(255, 255, 255, 0.5) in RGBA.
