The logo is formed of two parts, a light bulb and the text. The light bulb suggests the artistic part, branding and design and also the UI compound of what Mediagate does, the colors stand for imagination, dynamism and the light bulb itself stands for ideas, creativity.
The "E" is the socket of the light bulb, linking it to the text. The grey color of the font, together with the font itself, suggest the technical part of Mediagate. The letters give the sense of firm, serious, technical.
