Like blues/blacks, reds/burgundy, platinum/silver/gold and combinations of those (e.g. blue with gold or black with silver etc.); open to other ideas as well.

Design - would like to incorporate combination of symbols of a rook chess piece and citadel shape(s) if possible (see attached for examples). Please note that I prefer a rook chess piece (or a variation of its elements) as a principal focal point of the design. If unable or impractical to combine the design elements of rook and citadel, then focus on the rook chess piece elements only. Symbols are my preference, but open to using initials or abstract design ideas.

Colors - my comments on colors are just a starting point. Please feel free to use color combinations you consider appropriate/appealing based on your experience.

Text - open to either with or without company name; also could be either full name or partial (Citadel, Citadel Consulting or full Citadel Consulting Group).

Overall concept: As you think about the design, it may help to consider this: a citadel is a small but strong fort within, or a part of, a larger fortification, and served as a stronghold into which people could go for shelter during a battle.
