Re: [sc-dev] [commit] Color-==

[Till Bovermann <tboverma@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hey again,

so this should do the trick?

+ Color {
	== {|that|
		^(that.respondsTo(#[\red, \green, \blue, \alpha])
			and: {(this.red  == that.red)
			and: {this.green == that.green}
			and: {this.blue  == that.blue}
			and: {this.alpha  == that.alpha}
		})
	}

	hash { ^red.hash bitXor: green.hash bitXor: blue.hash bitXor:  
alpha.hash }
}


regards
Till
