That's great, Jodie! You're off to a very good start.
Since you're new to coding, be sure to follow the "Getting Started with Mini Micro" series that begins here. You're already past Day 1, but shortly I'll post Day 2, which will explain how to find and run the built-in demos.
But just for fun, since you already found the "graphics" commands, let me give you a couple of things to try:
text.color = color.blue
The first command changes the text color to blue. That's a little hard to read on a black background, so the second command above changes the background to pink. In this way, you can customize your Mini Micro environment and make it your own!
Wonder what other colors are available? Enter
all by itself. You should get a list of the built-in color names. (And their values, which are HTML color codes.) Have fun!
