Description
-----------

A color is represented as red, green and blue (r,g,b) components. Additionally, "a" represents the alpha component, often used for transparency. Values are in floating point and usually range from 0 to 1.  Some methods (such as set_modulate(color)) may accept values > 1.

Member Function Description
---------------------------

.. _class_Color_Color:

- :ref:`Color<class_color>`  **Color**  **(** :ref:`float<class_float>` r, :ref:`float<class_float>` g, :ref:`float<class_float>` b, :ref:`float<class_float>` a  **)**

Constructs a color from an RGBA profile using values between 0 and 1 (float).

::

    var c = Color(0.2, 1.0, .7, .8) # a color of an RGBA(51, 255, 178, 204)

.. _class_Color_Color:

- :ref:`Color<class_color>`  **Color**  **(** :ref:`float<class_float>` r, :ref:`float<class_float>` g, :ref:`float<class_float>` b  **)**

Constructs a color from an RGB profile using values between 0 and 1 (float). Alpha will always be 1.

::

    var c = Color(0.2, 1.0, .7) # a color of an RGBA(51, 255, 178, 255)

.. _class_Color_Color:

- :ref:`Color<class_color>`  **Color**  **(** :ref:`int<class_int>` from  **)**

Constructs a color from a 32-bit integer (each byte represents a component of the RGBA profile).

::

    var c = Color(274) # a color of an RGBA(0, 0, 1, 18)

.. _class_Color_Color:

- :ref:`Color<class_color>`  **Color**  **(** :ref:`String<class_string>` from  **)**

Constructs a color from an HTML hexadecimal color string in ARGB or RGB format.

The following string formats are supported:

``"#ff00ff00"`` - ARGB format with '#'

``"ff00ff00"`` - ARGB format

``"#ff00ff"`` - RGB format with '#'

``"ff00ff"`` - RGB format

::

    # The following code creates the same color of an RGBA(178, 217, 10, 255)
    var c1 = Color("#ffb2d90a") # ARGB format with '#'
    var c2 = Color("ffb2d90a")  # ARGB format
    var c3 = Color("#b2d90a")   # RGB format with '#'
    var c4 = Color("b2d90a")    # RGB format

.. _class_Color_blend:

- :ref:`Color<class_color>`  **blend**  **(** :ref:`Color<class_color>` over  **)**

Returns a new color resulting from blending this color over another color. If the color is opaque, the result would also be opaque. The other color could then take a range of values with different alpha values.

::

    var bg = Color(0.0, 1.0, 0.0, 0.5) # Green with alpha of 50%
    var fg = Color(1.0, 0.0, 0.0, .5) # Red with alpha of 50%
    var blendedColor = bg.blend(fg) # Brown with alpha of 75%

.. _class_Color_contrasted:

- :ref:`Color<class_color>`  **contrasted**  **(** **)**

Returns the most contrasting color.

::

    var c = Color(.3, .4, .9)
    var contrastedColor = c.contrasted() # a color of an RGBA(204, 229, 102, 255)

.. _class_Color_gray:

- :ref:`float<class_float>`  **gray**  **(** **)**

Returns the color's grayscale.

The gray is calculated by (r + g + b) / 3.

::

    var c = Color(0.2, 0.45, 0.82)
    var gray = c.gray() # a value of 0.466667

.. _class_Color_inverted:

- :ref:`Color<class_color>`  **inverted**  **(** **)**

Returns the inverted color (1-r, 1-g, 1-b, 1-a).

::

    var c = Color(.3, .4, .9)
    var invertedColor = c.inverted() # a color of an RGBA(178, 153, 26, 255)

.. _class_Color_linear_interpolate:

- :ref:`Color<class_color>`  **linear_interpolate**  **(** :ref:`Color<class_color>` b, :ref:`float<class_float>` t  **)**

Returns the color of the linear interpolation with another color. The value t is between 0 and 1 (float).

::

    var c1 = Color(1.0, 0.0, 0.0)
    var c2 = Color(0.0, 1.0, 0.0)
    var li_c = c1.linear_interpolate(c2, 0.5) # a color of an RGBA(128, 128, 0, 255)

.. _class_Color_to_argb32:

- :ref:`int<class_int>`  **to_argb32**  **(** **)**

Returns the color's 32-bit integer in ARGB format (each byte represents a component of the ARGB profile). More compatible with DirectX.

::

    var c = Color(1, .5, .2)
    print(str(c.to_32())) # prints 4294934323

.. _class_Color_to_html:

- :ref:`String<class_string>`  **to_html**  **(** :ref:`bool<class_bool>` with_alpha=True  **)**

Returns the color's HTML hexadecimal color string in ARGB format (ex: ``ff34f822``).

Optionally flag 'false' to not include alpha in hexadecimal string.

::

    var c = Color(1, 1, 1, .5)
    var s1 = c.to_html() # Results "7fffffff"
    var s2 = c.to_html(false) # Results 'ffffff'

.. _class_Color_to_rgba32:

- :ref:`int<class_int>`  **to_rgba32**  **(** **)**

Returns the color's 32-bit integer in ARGB format (each byte represents a component of the ARGB profile).

::

    var c = Color(1, .5, .2)
    print(str(c.to_32())) # prints 4294934323



*This is same as :ref:`to_ARGB32<class_Color_to_ARGB32>` but may be changed later to support RGBA format instead*.
