When you hit your Apple Watch’s side button, just under the Digital Crown, you get a list of the contacts you‘ve marked as Favorites in order to send your heartbeat or taps to them via Digital Touch, or folks you want to text with using your new Apple wrist gadget.
There are seven different presets for color coding those contacts, too, which default to red, blue, green, yellow, orange, white and purple.
Did you know that you could customize the colors of each of these seven slots? Here’s how.
First up, press the side button when your Apple Watch is awake, and get to the contacts screen. Tap on one of your favorites that has an Apple Watch, like you’re going to send your heartbeat.
Up in the top right corner of the Digital Touch screen is a little colored circle. That’s the color your contact is currently assigned. If you tap that circle, you’ll get the flower-like layout of the default 7 colors.
To change any one of these seven colored circles, simply tap and hold on the circle you want to edit. You’ll get a full-on color wheel that you can use to select any in-between color you like (except white or black) using the Digital Crown, or by dragging the little circle on the color wheel to the color of your choice.
I prefer using the Digital Crown because then you can see what color you’re changing to, but your mileage may vary. Enjoy! Now your Apple Watch’s Digital Touch contact wheel will work for your own color sense when you customize the contact circles.
