At the start of class I gave students grey colour chips to sort. Then I gave them colour chips.
We looked at the Hue Saturation Brightness (HSB), Red Green Blue (RGB) and Cyan Magenta Yellow Black (CMYK) colour systems. I spoke a little bit about Pantone too.
I finished correcting the exam we did last week. I have sent an email with the results anonymised. This histogram of the results looks something like the bar chart above. They are very disappointing.
