Creates a YIQ colour object from fractional values 0 .. 1.
Color::YIQ.new(0.3, 0.2, 0.1)
Creates a YIQ colour object from percentages 0 .. 100.
Color::YIQ.new(10, 20, 30)
Compares the other colour to this one. The other colour will be converted to YIQ before comparison, so the comparison between a YIQ colour and a non-YIQ colour will be approximate and based on the other colour‘s to_yiq conversion. If there is no to_yiq conversion, this will raise an exception. This will report that two YIQ values are equivalent if all component colours are within 1e-4 (0.0001) of each other.
