For lift (or offset) this is the value that will be added to every input color:

For gain, this is the value that will be added to the absolute white of the channel and will decrease to zero as the input color goes to zero:

For gamma, this is the number that will be added to power to which the input value of the channel will be raised (this is totally unintuitive, so different software gives you different interpretation of the gamma input - but it does the same):

Brighter colors become darker or brighter - the brighter the color the stronger the difference, blacks stay the same.

Most other color-correction plugins and apps usually assume this terminology (Apple Color, Colorista and all the others).
