Changing Google calendar colours

I am a colour junkie. So when I create new sub-calendars in Google, I change the sub-calendar colour to fit with the organisation I am delivering that collection of tasks for, as an additional aide-memoire.

However, each year I struggle to remember HOW to change the sub-calendar colour. I can create calendars hand-over-fist, but changing the colour is simply not an intuitive thing. Each year I expect the option to be in the calendar settings itself, and each year I have to search online - usually wasting a couple of hours - until I stumble across the setting again... usually by accident. 

So here are the instructions!

We create the calendar. We invite those whom we want to send a link to. Then we go out of the calendar settings. We create a couple of appointments for that calendar. Then, in our normal Calendar page view, in the left-hand pane, under the "My calendars" list, we click the three flaming menu dots alongside the new sub-calendar. And lo! The colour options pop up.

Sigh.
