§ 19.6.1.6 - Subtract

This mode subtracts the content of the higher layer from the lower layers. Where the result would be negative, the result is limited to the lowest values of the channel. For example, if channel value 6 is subtracted from channel value 4, the result will be channel value 0.

Where the higher layer is partially transparent, the result is mixed with the lower layer composite in a manner proportional to the amount of transparency.
