What other programs/plugins are you running?

Only OneBlock-chat does stuff with MineDown, OneBlock-fancyresources has some replacements using Adventure in it.

What is happening?

When using &#666&test_message syntax, message doesn't get colored. It happens only with rgb, &gold&test_message syntax works correctly. Full HEX syntax (#ff00ff&Text) doesn't work either.

What did you expect to happen?

&#666&test_message displays as test_message with #666 HEX color on it.

Additional context
