HEXA to OKLAB
Color Converter

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.

The OKLAB color space is a perceptual color space designed by Björn Ottosson in 2020. It serves as a modern improvement over the traditional CIELAB space, aiming to be simple to use while correcting flaws in LAB's perceptual uniformity, especially in the handling of blue hues which can appear purple in LAB. OKLAB uses three coordinates: 'L' for perceived lightness, 'a' for green-red, and 'b' for blue-yellow. Its superior perceptual accuracy makes it excellent for tasks like color blending, gradient generation, and image processing.
