Static methods:

• public static Color? alloc ()
  Allocates a new, transparent black Color.
• public static unowned Color? get_static (StaticColor color)
  Retrieves a static color for the given color name

Creation methods:

• public Color.from_hls (float hue, float luminance, float saturation)
  Converts a color expressed in HLS (hue, luminance and saturation) values into a Color.
• public Color.from_pixel (uint32 pixel)
  Converts pixel from the packed representation of a four 8 bit channel color to a Color.
• public Color.from_string (string str)
  Parses a string definition of a color, filling the red, green, blue and alpha fields of color.

Methods:

• public Color add (Color b)
  Adds this to b and saves the resulting color inside result.
• public Color? copy ()
  Makes a copy of the color structure.
• public Color darken ()
  Darkens this by a fixed amount, and saves the changed color in result.
• public bool equal (Color v2)
  Compares two Color<!-- -->s and checks if they are the same.
• public void free ()
  Frees a color structure created with copy.
• public uint hash ()
  Converts a Color to a hash value.
• public unowned Color? init (uint8 red, uint8 green, uint8 blue, uint8 alpha)
  Initializes this with the given values.
• public Color interpolate (Color final, double progress)
  Interpolates between this and final Color<!-- -->s using progress
• public Color lighten ()
  Lightens this by a fixed amount, and saves the changed color in result.
• public bool parse_string (string str)
• public Color shade (double factor)
  Shades this by factor and saves the modified color into result.
• public Color subtract (Color b)
  Subtracts b from this and saves the resulting color inside result.
• public void to_hls (out float hue, out float luminance, out float saturation)
  Converts this to the HLS format.
• public uint32 to_pixel ()
  Converts this into a packed 32 bit integer, containing all the four 8 bit channels used by Color.
• public string to_string ()
  Returns a textual specification of this in the hexadecimal form <literal>&num;rrggbbaa</literal>, where <literal>r</literal>, <literal >g</literal>, <literal>b</literal> and <literal>a</literal> are hexadecimal digits representing the red, green, blue and alpha components respectively.

Fields:

• public uint8 red
• public uint8 green
• public uint8 blue
• public uint8 alpha
