In her class today, the students had built the MIT “Digital Doodle” tutorial, which lets you draw on the tablet using a Canvas component (see http://explore.appinventor.mit.edu/sites/all/files/hourofcode/DigitalDoodle_2perpage.pdf). The key bit of code looks like this (from Page 7 of the tutorial):

A few of the students figured it out. Here’s the code from one of the groups:
The new part is the “Set Canvas PaintColor” command, plus the use of a color block.
I asked the students who figured it out to share the solution with each other.
