Made by yorshex
Insert the Unit RGB values into the two vectors fogColor1 (top colors) and fogColor2 (bottom colors) and click on the right arrow button on the bottom left of the textbox to reload the gradient image.
Note: This code won't let you see how much the fog leaps on the boxes in segments.
