The bug was set to WONTFIX and ignored. It was brought up in meetings on occasion (to some hilarity). Took a surprising amount of time for people to realize it wasn’t going to get resolved without a specification. There might have been some cultural differences at play, but mostly I think the Japanese company we dealt with had almost as little insight into Docomo as us half a world away.

The secret color chart eventually surfaced during compliance testing, the bug was resolved, and everyone lived happily ever after.
