The symbol "🔳🔲" represents a contrasting arrangement of two shapes, a square and a rectangle, one filled and the other empty. It embodies a visual duality, with the square denoting solidity and completeness while the rectangle suggests openness and potential. This composition evokes a sense of balance and harmony in its stark yet harmonious contrast. The word "dimidiate" relates to this description as it means to divide or cut something into two equal halves, which echoes the divided nature of the symbol.
