While I wish Apple Watch faces supported more customization, I really like the ability to change the colors. My standard is the Modular face with a color I select each morning that matches my shirt color. Really. To make that a little easier (and mostly because I was curious and couldn't find this list anywhere) I collated the Apple Watch face colors and created the reference below:
|Color Name||Hex Value|
Values were taken from screenshots of the Modular watch face on watchOS 5.0, AirDropped into Preview on a Mac with Digital Color Meter with
Display native values selected. The hour/minute separator was sampled around the same location for every color.
I've often thought there wasn't much variation between some of the shades on the Apple Watch. It was surprsing to me how distinctive some of the colors looked on my desktop display (a Dell P2715Q). I suspect it has more to do with seeing all the colors next to each other and not a deficiency in the Apple Watch's OLED screen's color rendition.
