I am having trouble with connecting into BrandMeister today. I know there have been some issues, but others seem to be operating OK. If I set a busy talkgroup from the OS 2 "Tools" menu, it receives the traffic, but won't allow me to transmit. The talkgroup is shown correctly on the info page for my callsign on BrandMeister. I am using the Ireland BM Master server.
What does "Color code mismatch in received stream from modem" mean?

You might have an error rate problem, the colour code is part of the header for DMR and is a bit like CTCSS in an analogue system.
Try shifting the frequency of your Tx a little each way and see if it improves.

Please run DMR AutoCal, or manually adjust the RX offset on the Modem page for the lowest BER. You can test your voice using the OS2's built-in local echo service on DMR ID 9999.

I have manually adjusted the OS2 for minimum BER, it needed a +500 Hz offset. I have checked the hand held using a commercial grade Racal counter with GPS locked standard and it is +21 Hz, which isn't bad for a Chinese hand held.
All sorted, it was the frequency difference by the look of it.
BTW, where is the DMR Autocal located?

It's a special connector, so you'll find it on the Connectors page.
