.new(values, mode = :rgb) ⇒ Object

Provides a thin veneer over the Color module to make it seem like this is Color 0.1.0 (a class) and not Color 1.4.1 (a module). This “constructor” will be removed in the future.

mode = :hsl

values must be an array of [ hue deg, sat %, lum % ]. A Spectrum::HSL object will be created.

mode = :rgb

values will either be an HTML-style colour string or an array of [ red, green, blue ] (range 0 .. 255). A Spectrum::RGB object will be created.

mode = :cmyk

values must be an array of [ cyan %, magenta %, yellow %, black % ]. A Spectrum::CMYK object will be created.
