For additional notes that apply to this portion of the standard, please see the notes for blue, §22.214.171.124.4(a) .
a. The standard states that element lumOff shifts the input color's luminance while leaving hue and saturation unchanged.
This element is not supported by Office and may produce unexpected color.
b. The standard states that ST_PositiveFixedPercentage is read and written as a percent with a trailing percent sign.
Office will read in percentages formatted with a trailing percent sign or as 1000th of a percent without trailing percent sign, but only write out percentages as 1000th's of a percent without trailing percent sign.
