The figure shows a 3D graphical interpretation of the HSL model (a), the image is taken from /wiki/. It is often used for computer graphics applications such as color pickers and image analysis. The HSL representation rearranges the colors to make them more intuitive than the RGB representation. In the HSL model, colors of each hue are arranged in a radial slice around a central axis of neutral colors, ranging from black at the bottom to white at the top. The HSL(Hue, Saturation, Lightness) color model was developed in the 1970s by computer graphics researchers to more closely match how human vision perceives color-producing attributes.

Many people consider the RGB color code is non-intuitive and hardware-oriented. The figure shows RGBA values of the color name “Yellow-Green” with different transparency:įor an RGBA value, unlike RGB values, there is no hexadecimal notation. For example, rgba(255, 0, 0) is displayed as pure red, rgba(255, 0, 0, 0.5) is displayed as red with 50% opacity. The alpha parameter is a number between 0.0, meaning “fully transparent”, and 1.0, meaning “fully opaque”. RGBA(Red, Green, Blue, Alpha) color values are an extension of RGB color values with an alpha channel that determines the opacity of the color. For example, #00FF00 is displayed as green, because the green component is set to its maximum value (FF) and the others are set to 00. The code is expressed as follows: #RRGGBB, where each of the two-digit values is a range of each of the three colors (red, green, blue), with which you select the final value representing each color. This gives over 16 million possible colors. Each two-digit hex pair can have a value from 00 to FF. The six-digit color number is structured into three groups of two digits which specify the amount of Red, Green, and Blue in the additive color. HEX codes are three-byte hexadecimal numbers (six variables). For example, the RGB color system can be represented as a cube with 255 discrete points on each side: One of the most typical ways to convey color is through visual systems such as diagrams or graphical models where each color has its own individual set of coordinates. Mixing these three colors would give you a RGB color code represented, for example, like this RGB(125,50,210).
So, there can be 256^3 = 16,777,216 different RGB colors in total. Since there are 256 different quantity options for each color. RGB is a popular color code model in photography, television, and computer graphics. The values R, G and B are the intensity (in the range from 0 to 255), respectively, of the red, green and blue components of the determined color.

It is the basis of the color displayed by light on TV screens, computers, image scanners, video projectors, digital cameras and mobile devices. RGB (Red, Green, Blue) is an additive color model that describes how any color is encoded using three basic ones. They are mainly used by web designers, front-end developers, programmers and digital illustrators. Color codes are used in HTML and CSS to create web design color schemes. HTML color codes are a means of representing a color format that a computer can read and display. The figure illustrates 16 basic colors with HEX and RGB codes: The 16 basic colors are aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow. W3C specification of color names distinguishes basic and extended colors. In HTML and XHTML, colors can be used for text, background, frame borders, tables, and individual table cells. For example, HTML colors may be specified as the common English color names, or with HEX values, RGB triplets, HSL, RGBA, and HSLA values.Ĭolors play an essential role in forming the perceived value of web content and the emotions a person experiences when viewing it. They are closely linked to the methods of describing and defining these colors using their respective color codes. HTML colors are the colors used to display web pages on the web.
