Compares this color to another one by looking at their associated color spaces and their

    components == other.components && color_space == other.color_space
end

* If the color value is less than 0.0, it is set to 0.0.
* If the color value is greater than 1.0, it is set to 1.0.
* If the color value is an Integer, it is converted to a float and divided by +upper+.

The conversion is done in the following way:

Normalizes the given color value so that it is in the range from 0.0 to 1.0.

def normalize_value(value, upper)
  value = value.to_f / upper if value.kind_of?(Integer)
  value.clamp(0, 1)
