If you were after something short and incomprehensible, you could use:

  <path fill="{substring('yellow green',
                         (fill_percentage > 90) * 7 + 1, 6)}" />

if fill_percentage > 90 is true (1), then multiplying by 7 gives you 7,
plus 1 is 8, so you get the substring of 'yellow green' starting at
the 8th character ('g') and 6 characters long (the rest of the
string). If fill_percentage > 90 is false (0), then multiplying by 7
gives you 0, plus 1 is 1, so you get the substring of 'yellow green'
starting at the 1st character ('y') and 6 characters long (the string
'yellow').

Cheers,

Jeni
