In the development environment, to display and display the desired color you need to know its code. Different programming languages and web (HTML, JavaScript, CSS) have their own formats, the most common being RGB, HSV and Hex. In turn, the W3C specification defines 16 primary and 130 shades of color names. To understand which format is written in a color code, you need to know how it is designated.

RGB color code (Red,Green,Blue) is written in the form of (*, *, * ) in which the “*” indicates the amount of tone (red, green, blue) in a given color. Values range from 0 to 255.
There is also the RGBA (r,g,b,a) format, where the ‘a’ (alpha) parameter indicates support for an alpha channel to define the opacity of the object. This is between 0.0 (transparent) and 1.0 (opaque) – (150, 100, 200, 0.3).
HSV standard with the view (210, 79%, 34%) coordinates:
- Hue – color tone in degrees from 0° to 360°;
- Saturation – the saturation value in units of 0-1 or 0-100. The smaller is this parameter, the closer the color becomes to grayish neutral. The greater the value, the more saturated. This option is also called color purity;
- Value – the color value, which sets the brightness. It is measured in units of 0-100 or 0-1.
Hex format is represented as three pairs of character values #ffa800, written in hexadecimal notation. The first pair denotes red saturation, the second pair denotes green saturation, and the third pair denotes blue saturation. Specified in units of 0 to 9 and English letters a to f.
Color Picker
With the HTML color picker you have the possibility to choose a suitable tone or enter values manually to check. The color code is displayed in RGB and Hex formats. The converter serves mainly for CSS.

The safe palette color table
The HTML specification defines 16 primary colors with names that can be used as keywords as values. There are also codes in Hex and RGB formats.
