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.
.. rst-class:: classref-introduction-group
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:
.. rst-class:: classref-enumeration
enum **Function**:
.. _class_VisualShaderNodeColorFunc_constant_FUNC_GRAYSCALE:
.. rst-class:: classref-enumeration-constant
:ref:`Function<enum_VisualShaderNodeColorFunc_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);
.. _class_VisualShaderNodeColorFunc_constant_FUNC_SEPIA:
.. rst-class:: classref-enumeration-constant
:ref:`Function<enum_VisualShaderNodeColorFunc_Function>` **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);

- void **set_function** **(** :ref:`Function<enum_VisualShaderNodeColorFunc_Function>` value **)**
- :ref:`Function<enum_VisualShaderNodeColorFunc_Function>` **get_function** **(** **)**
A function to be applied to the input color. See :ref:`Function<enum_VisualShaderNodeColorFunc_Function>` for options.
