Hex color is a coding format that is used for computer graphics. It is a string of six hexadecimal digits, each between 0 and F.
The hex color format has been around since the 1980s, but it became popular in the 1990s when it was adopted by hardware manufacturers. It had been widely used in the PC gaming industry until HTML5 came into use. Some of its drawbacks include less readability and compatibility with older versions of browsers.
The RGBA color format is a way of expressing a color as an RGB triplet. This allows for greater flexibility when displaying colors visually in CSS, such as by using it to represent parts of the color spectrum.
RGBA stands for red, green, blue, and alpha - the opacity level of color.
The RGBA format is often used to specify how transparent or opaque an element should be in CSS.
