The alignment of labels is set towards the top of the colour swatch for the colour legend.  This is probably perfect for the banded colour lookup shown below.

However where there are multiline labels, the first line for each swatch is set too high.

May I suggest that the insertion point/alignment for each text label be set at the top of each swatch, rather than above the centre of each swatch as currently appears to be the case?
