If it's possible, it'll be easy to do. I've been thinking a bit about the other Civ4lert messages as well. For example, when a city is about to become unhappy, the whole message is orange.
Amsterdam will become unhappy next turn.
The problem for me (I have poor vision) is that with several orange messages, the only way to know which message it is and to which city it applies, I have to read the whole message.
I like the standard Civ messages that mix colors, using green for technologies and blue for cities, IIRC. This makes the important part of the message stand out, improving scannability.
So I'd change the above message to this:
Amsterdam will become unhappy next turn.
Similarly for "has become":
Amsterdam has become unhappy.
This would extend to the other messages.
Mansa Musa will trade
Horseback Riding.
Catherine will trade
240 .
What do you all think?
BTW, I think I have the color for leader names wrong, and city names may actually be white, but I'm not at my home PC. Obviously, I'd try to match these up to the existing messages where possible.
If city names are white, what color would you recommend to use instead?
