You don’t have to spend that long in playing with colour management before the word deltaE comes up, it is after all a very complex subject with words that you will have never even heard of cropping up in paragraph after paragraph of text you read on the subject. But ever wondered what those deltaE numbers really mean?
Well quite simply put it is a single number that represents the ‘distance’ between two colours. Simple right? Well no not really since it doesn’t really help you visualise what that will mean to your job, on top of that deltaE comes in a number of flavours….. go figure! Each one has its own way of calculating that difference.
So let’s take a quick peek at what this colour difference will actually mean in the real world. I must stress this is only a simulation based on dE76 and was created some time back when I needed to simulate this subject to someone…. I’m sure one of you complete diehard colour experts out there will correct me if this is to far wrong…..
