A HEXA color code often written as "hex with alpha" is a hexadecimal color representation that includes an alpha component, similar to the rgba color format. In this format, in addition to the standard six characters that define the red, green, and blue (RGB) components, two additional characters represent the alpha channel, which controls the color's transparency or opacity. The alpha channel ranges from 00 (completely transparent) to FF (completely opaque), allowing for a wide range of transparency levels in a color. This format is commonly used in web design and graphic design to specify colors with transparency, providing control over the visual appearance of elements on a web page or in digital graphics.
HSL color code, which stands for Hue, Saturation, Lightness, is a color representation system used in digital design and computing. Unlike RGB, which is based on the red, green, and blue primary colors, HSL focuses on different aspects of color.
HSL color codes provide a more intuitive and user-friendly way to work with colors, making it easier to adjust color attributes like hue, saturation, and lightness for various design purposes in web and graphic design.
