Schwarz-weiß wie Schnee
You talkin' to me?!
It just means the chip you play applies bonus effects as normal.
The wording in the almanac says: "If the newly laid chip also has a bonus, it can also be carried out immediately." So to carry out the bonus, you simple do what the bonus says. And what do they say? Black, green, and purple all say "In Evaluation Phase B, ...", so if you follow the words of carrying out the bonus literally, you're still stuck waiting.
This means if another blue chip is drawn you can carry out it's bonus too.
