A clean, professional, corporate monogram logo on a solid light-grey background. The main element is a large, geometric letter 'D', which has an 'O' shape cut out from its right side, creating a clear 'DO' or 'D O' monogram with clean lines. It uses a gradient from dark grey to black, creating a sense of 3D depth and layers. Below the main icon, in a smaller, simple, black sans-serif font, is the two-line text "DESIGN CONSULTANCY".
