Oklab to xvYCC Converter - Color Space Converter

Also known as the Oklab color space.There are 3 channels in total, L,range from 0 to 1.a,range from -0.4 to 0.4.b,range from -0.4 to 0.4.

OKLab is a perceptually uniform color space developed by Björn Ottosson, designed as a simple and computationally efficient color space that closely aligns with human vision.

OKLab color space.

In the OKLab color space, colors are represented by Lightness (L), green-red chroma component (a), and blue-yellow chroma component (b).

OKLab is commonly used for tasks where color difference is important, such as color grading, graphic design, and image processing.

Due to its perceptual uniformity and simplicity in computation, OKLab is particularly useful in color editing and image analysis.

Also known as the xvYCC color space.There are 3 channels in total,Y,range from 0 to 255.Cb,range from 0 to 255.Cr,range from 0 to 255.

xvYCC was developed by Sony and standardized by the International Electrotechnical Commission (IEC) in 2005. It is an expansion over the standard YCbCr color space, designed to support a wider range of colors for high-definition video.

The main name is xvYCC, also known as IEC 61966-2-4 or extended-gamut YCC.

Similar to YCbCr, xvYCC is typically expressed as three component values (Y, Cb, Cr). However, xvYCC uses a signaling method that enables it to represent a broader range of colors. This includes values for Cb and Cr that, unlike YCbCr, can exceed the nominal range of video levels, going below 16 or above 235 in 8-bit terms.

xvYCC is used primarily in high-definition video formats and devices such as Blu-ray players, digital cameras, and HDTVs that support HDMI 1.3 or higher. It allows for more vivid and accurate color representation on capable devices.

xvYCC can display a wider range of color values than sRGB by allowing values that fall outside the typical RGB gamut. It achieves this by using the same color encoding method as YCbCr but permits values in the signaling that exceed the range of the BT.601 or BT.709 color spaces.
