CalculatorHub logo concepts

Twenty-five directions to replace the current mark, each tuned to what makes CalculatorHub different: thousands of free calculators where every figure traces to an official source and is built to be cited. The brand colours stay constant (deep green for trust, a single gold accent for the verified answer) so any of these reads as one family.
