lum (Luminance)

This element specifies the input color with the specified luminance, but with its hue and saturation unchanged. Typically luminance values fall in the range [0%, 100%].

[Example:

The following two solid fills are equivalent: 

<a:solidFill>
  <a:hslClr hue="14400000" sat="100.000%" lum="50.000%">
</a:solidFill>
<a:solidFill>
  <a:hslClr hue="14400000" sat="100.000%" lum="0%">
    <a:lum val="50%"/>
  <a:hslClr/>
</a:solidFill>

end example]

Specifies the value of the blue component. The assigned value is specified as a percentage with 0% indicating minimal blue and 100% indicating maximum blue.

<a:solidFill>
  <a:srgbClr val="00FF00">
    <a:blue val="100.000%"/>
  </a:srgbClr>
</a:solidFill>

end example]

The possible values for this attribute are defined by the ST_Percentage simple type (§20.1.10.40).
