LabelColor not responding for Passbook

Question

My whole environment in Passbook works fine (a server based on PHP / MySQL for generating and signing a password, as well as downloading a pass - downloading based on a web view, emailing a pass or presenting it in my application using PassKit).

The only thing that does not work is the color of the Color label in the primary fields of the coupon type.

I have (in pass.json file):

"foregroundColor" : "rgb(30, 30, 30)",
"backgroundColor" : "rgb(230, 230, 230)",
"labelColor" : "rgb(30, 30, 30)",

The foregroundColor and backgroundColor colors work fine, but the labelColor (shown on top of the strip image) is white, not the specified labelColor.

As recommended by Apple Passbook, labelColor is optional

"Optional. The text color of the label specified as a CSS-style RGB triple. For example, rgb (255, 255, 255). If this parameter is omitted, the color of the label is determined automatically."

In this case, the image of the strip is a clear image, so the text should be black (even if the labelColor is omitted and the color is determined automatically), but the attempt appears white in the passage

Any help would be appreciated.

Answer 1

Label and foreground colors apply only to primary field labels and values ​​when there is no strip image in the aisle. If a strip image exists, the text color automatically changes to white.
