Discussion

This color space has the same colorimetry as sRGB, but you can encode component values below 0.0 and above 1.0. Negative values are encoded as the signed reflection of the original encoding function, as shown in the formula below:

extendedTransferFunction(x) = sign(x) ✖️ sRGBTransferFunction(abs(x))
