In the last talk-through, we explored how to use the color picker to easily find a color. Since you can't see the color picker in action in our talk-throughs, here's a GIF of it being used:
Click anywhere in the numbers to get the color picker to pop up. Then, click on the right hand color bar to change the general color you're picking, and click in the left hand side to change the lightness/brightness of the color. You'll get to try it in the next challenge!
