-These functions are calculated before getting the RGB color from the palette. They only manipulate colorValues, so they need a range of colorValue inputs to work. These functions are global and work on the whole palette. The default palette is linear, with the colors spaced evenly apart, with a smooth symmetrical transition between each of them. The first three "curve" functions effectively deform the palette such that the colors are no longer evenly spaced.
+These functions add a varying value to the Final ColorValue. The starting point of the function along the palette can be set, so as to control the location of the beginning of the deformation.
