What exactly is the color variable being used for?

Hi there,

Struggling to understand why Andrew is using the color variable. Why is it there? Everything still seems to work fine without it.

Thanks, James.

You're right that it doesn't seem to make a difference at the moment, but further on when new features are added to the application for adding new colors and the drawing functionality itself, storing the color in a variable will become essential.

Hi James,

Did you ever find the answer to your question? As Joel Bardsley commented, the color variable will be used by the application to know what color the lines should be when the user draws on the canvas.

If it still doesn't make sense after you get to the end of the video Perform: Part 5, please let us know! We're happy to explain further.
