    [MS-OI29500] 2.1.1230 "Part 1 Section 20.1.2.3.20, lumMod (Luminance Modulation)" (https://docs.microsoft.com/en-us/openspecs/office_standards/ms-oi29500/bbae8916-01d7-48ac-ae07-ff5d30130967states: 

    For additional notes that apply to this portion of the standard, please see the notes for blue,
    §20.1.2.3.4(a)
    .
    a. 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.

    The value you entered translates to the emitted value of 75000 which is 1000th of a percent * 75000 or 75%. This means you've reduced the luminance of the color by 25% or to 75%.
