Less - Color Blending Functions

In this chapter let's study about Color Blending Functions. These are similar operations used in image editors like Photoshop, Fireworks or GIMP, which matches your CSS colors to your images.
The following table shows the color blending functions used in LESS.

S.N.	Functions & Description
1	multiply It multiplies two colors and returns a resultant color.
2	screen It takes two colors and returns a brighter color. It works opposite of multiply function.
3	overlay It generates result by combining the effect of multiply and screen.
4	softlight It works similar to overlay but it uses only a part of the color, which soft-highlights the other color.
5	hardlight It works similar to overlay but the role of the colors reversed.
6	difference It subtracts the second input color from the first input color.
7	exclusion It works similar to difference function but with lower contrast.
8	average It computes the average of two input colors on a per-channel (RGB) basis.
9	negation It works opposite to difference function, which subtracts first color from second color.
