VisualShaderNodeColorFunc
=========================
**Inherits:** :ref:`VisualShaderNode<class_VisualShaderNode>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
A :ref:`Color<class_Color>` function to be used within the visual shader graph.
Description
-----------
Accept a :ref:`Color<class_Color>` to the input port and transform it according to :ref:`function<class_VisualShaderNodeColorFunc_property_function>`.

Enumerations
------------
.. _enum_VisualShaderNodeColorFunc_Function:
.. _class_VisualShaderNodeColorFunc_constant_FUNC_GRAYSCALE:
.. _class_VisualShaderNodeColorFunc_constant_FUNC_SEPIA:
enum **Function**:
- **FUNC_GRAYSCALE** = **0** --- Converts the color to grayscale using the following formula:
::
vec3 c = input;
float max1 = max(c.r, c.g);
float max2 = max(max1, c.b);
float max3 = max(max1, max2);
return vec3(max3, max3, max3);
- **FUNC_SEPIA** = **1** --- Applies sepia tone effect using the following formula:
::
vec3 c = input;
float r = (c.r * 0.393) + (c.g * 0.769) + (c.b * 0.189);
float g = (c.r * 0.349) + (c.g * 0.686) + (c.b * 0.168);
float b = (c.r * 0.272) + (c.g * 0.534) + (c.b * 0.131);
return vec3(r, g, b);
