business to business sales lead

What does the company long term "Blues" mean?
What does "Blue" means when talking about work in a sales environment for a business? I looked up and I'm not sure what this term means, it means developing new companies without an advantage? Friendly and helpful answers are appreciated.
"Blueprint" is the action plan, guidelines for setting implementation, development, deployment, and therefore a plan is also a product itself: it was designed, developed, discussed, is burst into the brain, approved, etc.
