Document Summary
Gcm 360 | week 4 - describing colour. We find it difficult to describe colour in words. Difficult to remember colours from last week or samples in different rooms. However, we are good at side by side comparisons. We find it difficult to remember colours from a job done last week, or if the sample is in another room. We cannot easily describe colour on the phone. Even though we just saw a colour, we cannot easily remember it. Better be knowing through side-by side comparisons. When measuring for process control, it is important to use relevant metrics . Marketing material often has diagrams are shown. As we have seen the colour space is distorted and is perceptually non-uniform. Despite these limitations, many large companies continue to use this diagram to. Take the shown ads with a grain of salt (don"t believe what shown is true) L* a* b* corresponds directly with how we see colour.
