Fill Definitions

This is where fills used in the workbook are expressed.

<fills count="1">
	<fill>
	<patternFill patternType="solid">
	<fgColor theme="4"/>
	<bgColor theme="4"/>
	</patternFill>
	</fill>
</fills>

This fill definition specifies a solid pattern fill, whose color uses a themed color, whose index is "4" in the <clrScheme> collection of the Theme part. A <fill> definition is referenced by index (fillId) from either a <cellXf> or a <cellStyleXf>.

A fill record is referenced by zero-based index, meaning the numerical order in which the fill appears under fills.
