I don't like people who are very black and white about things. Life, science, teaching, and politics are complicated. There are shades of grey. Simplistic analysis leads to simplistic "solutions". Hopefully I often bring that out in this blog, in posts such as a political metaphor for the correlated electron community.
Yet there is an issue where I am quite black and white and adverse to technicolour solutions (the rainbow coalition?!): power point slides.
Recently I sat through a talk where the speakers slides had every dot point in a different colour.
I really find this hard to read and distracting.
Yet this is not unusual.
What is wrong with plain old black and white and traditional fonts?
Below is a random choice of one of my slides. It is not very creative or glamorous but it is easy on the eyes and brain.
