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.
HSVA color code, an extension of the HSV color model, introduces an Alpha channel, resulting in Hue, Saturation, Value, and Alpha.
HSVA color codes are valuable in web design, graphic design, and digital art, enabling precise specification of colors with varying levels of transparency. This extension enhances control over the visual aspects and layering of elements in digital creations.
