The Color class represents RGBA color values using a value range of 0 to 255 inclusive. It allows basic arithmetic operations — binary operations +, -, *, //, %, and unary operation ~ — to create new colors, supports conversions to other color spaces such as HSV or HSL and lets you adjust single color channels. Alpha defaults to 255 (fully opaque) when not given. The arithmetic operations and correct_gamma() method preserve subclasses. For the binary operators, the class of the returned color is that of the left hand color object of the operator.

Color objects support equality comparison with other color objects and 3 or 4 element tuples of integers. There was a bug in pygame 1.8.1 where the default alpha was 0, not 255 like previously.

Color objects export the C level array interface. The interface exports a read-only one dimensional unsigned byte array of the same assigned length as the color. For CPython 2.6 and later, the new buffer interface is also exported, with the same characteristics as the array interface.

The floor division, //, and modulus, %, operators do not raise an exception for division by zero. Instead, if a color, or alpha, channel in the right hand color is 0, then the result is 0. For example:

# These expressions are True
Color(255, 255, 255, 255) // Color(0, 64, 64, 64) == Color(0, 3, 3, 3)
Color(255, 255, 255, 255) % Color(64, 64, 64, 0) == Color(63, 63, 63, 0)

Parameters:	r (int) -- red value in the range of 0 to 255 inclusive g (int) -- green value in the range of 0 to 255 inclusive b (int) -- blue value in the range of 0 to 255 inclusive a (int) -- (optional) alpha value in the range of 0 to 255 inclusive, default is 255 color_value (Color or str or int or tuple(int, int, int, [int]) or list(int, int, int, [int])) -- color value (see note below for the supported formats) Note Supported `color_value` formats: - Color object: clones the given `Color` object - color name str: name of the color to use, e.g. `'red'` (all the supported name strings can be found in the colordict module) - HTML color format str: `'#rrggbbaa'` or `'#rrggbb'`, where rr, gg, bb, and aa are 2-digit hex numbers in the range of 0 to 0xFF inclusive, the aa (alpha) value defaults to 0xFF if not provided - hex number str: `'0xrrggbbaa'` or `'0xrrggbb'`, where rr, gg, bb, and aa are 2-digit hex numbers in the range of 0x00 to 0xFF inclusive, the aa (alpha) value defaults to 0xFF if not provided - int: int value of the color to use, using hex numbers can make this parameter more readable, e.g. `0xrrggbbaa`, where rr, gg, bb, and aa are 2-digit hex numbers in the range of 0x00 to 0xFF inclusive, note that the aa (alpha) value is not optional for the int format and must be provided - tuple/list of int color values: `(R, G, B, A)` or `(R, G, B)`, where R, G, B, and A are int values in the range of 0 to 255 inclusive, the A (alpha) value defaults to 255 if not provided
Returns:	a newly created `Color` object
Return type:	Color

Changed in pygame 2.0.0: Support for tuples, lists, and Color objects when creating Color objects.

Changed in pygame 1.9.2: Color objects export the C level array interface.

Changed in pygame 1.9.0: Color objects support 4-element tuples of integers.

Changed in pygame 1.8.1: New implementation of the class.

r¶: Gets or sets the red value of the Color.

r -> int

The red value of the Color.

g¶: Gets or sets the green value of the Color.

g -> int

The green value of the Color.

b¶: Gets or sets the blue value of the Color.

b -> int

The blue value of the Color.

a¶: Gets or sets the alpha value of the Color.

a -> int

The alpha value of the Color.

cmy¶: Gets or sets the CMY representation of the Color.

cmy -> tuple

The CMY representation of the Color. The CMY components are in the ranges C = [0, 1], M = [0, 1], Y = [0, 1]. Note that this will not return the absolutely exact CMY values for the set RGB values in all cases. Due to the RGB mapping from 0-255 and the CMY mapping from 0-1 rounding errors may cause the CMY values to differ slightly from what you might expect.

hsva¶: Gets or sets the HSVA representation of the Color.

hsva -> tuple

The HSVA representation of the Color. The HSVA components are in the ranges H = [0, 360], S = [0, 100], V = [0, 100], A = [0, 100]. Note that this will not return the absolutely exact HSV values for the set RGB values in all cases. Due to the RGB mapping from 0-255 and the HSV mapping from 0-100 and 0-360 rounding errors may cause the HSV values to differ slightly from what you might expect.

hsla¶: Gets or sets the HSLA representation of the Color.

hsla -> tuple

The HSLA representation of the Color. The HSLA components are in the ranges H = [0, 360], S = [0, 100], V = [0, 100], A = [0, 100]. Note that this will not return the absolutely exact HSL values for the set RGB values in all cases. Due to the RGB mapping from 0-255 and the HSL mapping from 0-100 and 0-360 rounding errors may cause the HSL values to differ slightly from what you might expect.

i1i2i3¶: Gets or sets the I1I2I3 representation of the Color.

i1i2i3 -> tuple

The I1I2I3 representation of the Color. The I1I2I3 components are in the ranges I1 = [0, 1], I2 = [-0.5, 0.5], I3 = [-0.5, 0.5]. Note that this will not return the absolutely exact I1I2I3 values for the set RGB values in all cases. Due to the RGB mapping from 0-255 and the I1I2I3 mapping from 0-1 rounding errors may cause the I1I2I3 values to differ slightly from what you might expect.

normalize()¶: Returns the normalized RGBA values of the Color.

normalize() -> tuple

Returns the normalized RGBA values of the Color as floating point values.

correct_gamma()¶: Applies a certain gamma value to the Color.

correct_gamma (gamma) -> Color

Applies a certain gamma value to the Color and returns a new Color with the adjusted RGBA values.

set_length()¶: Set the number of elements in the Color to 1,2,3, or 4.

set_length(len) -> None

The default Color length is 4. Colors can have lengths 1,2,3 or 4. This is useful if you want to unpack to r,g,b and not r,g,b,a. If you want to get the length of a Color do len(acolor).

New in pygame 1.9.0.

lerp()¶: returns a linear interpolation to the given Color.

lerp(Color, float) -> Color

Returns a Color which is a linear interpolation between self and the given Color in RGBA space. The second parameter determines how far between self and other the result is going to be. It must be a value between 0 and 1 where 0 means self and 1 means other will be returned.

New in pygame 2.0.1.
