Method: Color::GrayScale#==

Defined in:
lib/coloration/color/grayscale.rb

#==(other) ⇒ Object

Compares the other colour to this one. The other colour will be converted to GreyScale before comparison, so the comparison between a GreyScale colour and a non-GreyScale colour will be approximate and based on the other colour’s #to_greyscale conversion. If there is no #to_greyscale conversion, this will raise an exception. This will report that two GreyScale values are equivalent if they are within 1e-4 (0.0001) of each other.
