3D Surface plot - how to set Colorscale range with our own value


I have 3 (x,y,z) axis values to plot 3D Surface plot. I use KDE function for z like z=KDE(x,y).
In such case, the colorscale ranges from 0 to 1 automatically. Is there any way to set/change the colorscale range using our own values/actual min and max of z values, instead of 0 to 1 ?.

It would be great, if anyone clarifies on this. Your solution/feedbacks are much appreciated in advance. THank you.
