 Color Balance Modifier
 ----------------------
 
-Color balance adjustments, through Lift, Gamma, and Gain.
+Color balance adjustments, either by the Lift, Gamma, and Gain or the Slope, Offset and Power method. 
 
-This modifier works the same as the :doc:`Color Balance Node </compositing/types/color/color_balance>`.
+This modifier works similar to the :doc:`Color Balance Node </compositing/types/color/color_balance>`.

+Depending on the selected method, the following operations can be applied to the color values in the 
+sequencer color space:
+
+Lift/Gamma/Gain
+   Lift
+      Increases the value of dark colors.
+   Gamma
+      Adjusts midtones.
+   Gain
+      Adjusts highlights.
+
+Offset/Power/Slope (ASC-CDL)
+   The following formula is applied to each RGB color value separately: :math:`c_{out} =  (c_{in}*s + o)^p`
+
+   Slope
+      The multiplier :math:`s` influences all color values except black. Its effect is stronger 
+      the brighter the source color is. 
+   Offset
+      Shifts color values after applying Slope by adding the Offset :math:`o` to them. Note that 
+      the selected value shown in the UI will be subtracted by 1, so the default value of 1 means 
+      effectively no offset is applied. 
+   Power
+      Over-all exponent :math:`p`, which mainly adjusts the midtones.
