Watch-face Clock bubble color customization
Starting v4.40 a 3rd option becomes available for the clock bubble:
►Analog clock: uploading images
►Digital clock: changing colors
►New: Analog clock: changing colors
You can now adjust the look of the analog clock bubble without the need of uploading dials, hour and minute hands.
1) you can change the color of non-customized clock component images
2) v4.40 also brings improvements in the way uploaded clock image components are handled. It became much more flexible: no need to size the pieces separately.
