Session 3: Colors

Make sure you have at least the red and green pens. Do not continue without them.

Using Colors

Try using hatching and stippling to create different intensities.

Can you provide shading to make the red... box(?) in your notes look 3-dimensional?

If you have a hard time seeing this object, I have taken a picture of it for you:

There are 5 faces that you can see. Which one (or two) is the darkest? Assign numbers (mentally) to indicate their relative darkness. You can then hatch or stipple in the increasing intensities like you had above.

We used red for "alert" and green for "things are OK". Why?

If your answer is that these come from traffic light, then that just brings it one step back: why was red used for stop, and green for go?

Is this just convention, or are we wired to feel a certain ways when we see particular colors?

If perception of colors triggers feelings in us biologically, what prevents malicious actors to use colors to influence how we feel?

Google Sheets: Conditional Formatting

Open this spreadsheet and Make a Copy.

Use conditional formatting to visualize the grades and identify if there are tests where students performed differently than their usual selves.

Surprisingly, this usage of colors, even though they add meaning and makes interpretation easier, is rather heavily frowned upon. This probably comes from conventions of print, where it used to be all black-and-white.

When you try to conditionally color your tables for other teachers, they might ask you to take the color away: "it's just not professional".

What should you do? What would you do? Why?

Expert TODO lists

Your homework this week will involve the Hong Kong rainfall data in a separate tab from the previous spreadsheet.

You need to use a color scale to visualize it, and add a "danger" color for when the rain was incredibly heavy.

Then you need to identify the month with the most rainy days and heaviest rainfall.

Your task here is NOT to do the homework, but to break down the homework into a sensible TODO list.

There is no correct answer here. How much you need to break down a task depends on your familiarity with the task. What you need to do is to reflect on the accuracy of your TODO list while you are using it. You get better with experience.

Homework

Hand in on ManageBac as two files: a screenshot and a PDF. This is due Sunday Sep 13.

1: Rainfall analysis

Your homework this week involves working with the Hong Kong rainfall data.

First, use a color scale to visualize it, and add a "danger" color for when the rain was incredibly heavy. (It's subjective.)

Second, for each month, calculate:

1. The average rainfall,
2. The number of rainy days, and
3. The number of days with Trace amount of rain

You will probably need to learn some new spreadsheet functions to COUNT things and COUNT-things-IF. (hint, hint)

2: Pomodoro Drawing

Draw me two Pomodoro timers, the first one in 2D (just lines), and the second one in 3D (with stippling or hatching). Use colors. Scan these as PDF with Office Lens.
