## **Tutorial Steps**

---

** **In this tutorial, we create color variations over the hair using the VRayHairNextMtl and VRayHairInfoTex.

### **Apply VRayHairNextMtl to hair system**

1. Start by adding a VRayHairNextMtl to the hair object and set the preset to use the **Sandy Blond **preset as a basis.
  
2. Do a test rendering to see the result.

### **Set up Nodes**

1. Create a **VRayHairInfoTex** node.
  
2. ** **Connect the **output** of the **VRayHairInfoTex** node to the **Diffuse color** slot of the **VRayHairNextMtl**.  
   
  
 ** **> Macro (inline-media-image)

  
** **  
** **
3. ** **In the **VRayHairInfoTex **parameters, either the **Position along strand **or **Random by strand index** parameter can be selected for the node's output.  
  
   
 ** **> Macro (inline-media-image)


### **Color the Hair**

1. Open the **VRayHairInfoTex** ** **and set **color A** and **color B** to turquoise and pink respectively, as shown below. The **Random by strand index** option allows different strands to receive different colors, as opposed to changing the color along the strand of each hair when using **Position along strand**.
  
2. Experiment with different colors and **bias** values in the **VRayHairInfoTex** to achieve the desired look.

 

### Examples

 

> Macro (ui-text-box)
> 
> Real-world hair or fur does not have a **diffuse** component. Although the diffuse parameter allows for some artistic control, for realistic results it is best to disable it by leaving the **diffuse amount** at 0.
> 
> In the examples above, we have linked the VRayHairInfoTex node to the **Diffuse color** slot of the VRayHairNextMtl only for a representative purpose as it makes the effect of the texture more prominent.
