Instance Method Details

#blue ⇒ AbcDecimal

Returns the blue component of the color in sRGB color space.

This method converts the current color to sRGB if needed and extracts the third coordinate value (blue).

Returns:

  • (AbcDecimal) —

    The blue component value in sRGB space, typically in range 0-1

end

#green ⇒ AbcDecimal

Returns the green component of the color in sRGB space.

This method converts the current color to sRGB color space if needed, then extracts the green component (second coordinate).

Returns:

  • (AbcDecimal) —

    The green component value in the sRGB color space, typically in the range 0-1

#red ⇒ AbcDecimal

Returns the red component of the color in the sRGB color space.

normalized between 0 and 1.

Returns:

  • (AbcDecimal) —

    The red component value in the sRGB color space,

end

#rgb_array ⇒ Array<Integer>

Returns an array of RGB values (0-255) for this color.

This method converts the color to sRGB, then scales the component values from the 0-1 range to the 0-255 range commonly used in RGB color codes. Values are rounded to the nearest integer and clamped between 0 and 255.

values in the 0-255 range

Returns:

  • (Array<Integer>) —

    An array of three integers representing the [R, G, B]

  to_srgb.coordinates.map { |c| (c * 255).round.clamp(0, 255) }
end

#rgb_hex ⇒ String

Returns a hexadecimal representation of this color in sRGB color space. Converts the color to sRGB, then formats it as a hexadecimal string.

the hexadecimal representations of the red, green, and blue components, each ranging from 00 to FF. color.rgb_hex #=> “#3a7bc8”

Returns:

  • (String) —

    A string in the format “#RRGGBB” where RR, GG, and BB are

#srgb_values ⇒ Array<AbcDecimal>

Returns the RGB color values in the sRGB color space.

the red, green, and blue color components in the sRGB color space.

Returns:

  • (Array<AbcDecimal>) —

    An array of three AbcDecimal values representing

end

#to_rgb! ⇒ self

Converts the current color to sRGB color space in place. This is an alias for #to_srgb! as RGB commonly refers to sRGB in web and design contexts.

Returns:

  • (self) —

    Returns self after converting to sRGB

end

#to_srgb ⇒ Abachrome::Color

Converts the current color to the sRGB color space.

If the color is already in the sRGB color space, returns the color instance unchanged. Otherwise, performs a color space conversion from the current color space to sRGB.

or self if already in sRGB

end

#to_srgb! ⇒ Abachrome::Color

Converts the color to the sRGB color space, mutating the current object. If the color is already in sRGB space, this method does nothing.
