The mark consists of a standard A19 halogen light bulb, with a silver socket base. The three capital letters 'SBS', in white color, appear vertically and perfectly centered in the light bulb. The white letters are against a purple backdrop, that then fades into a dark blue color, then a black color. Inside the bulb, at the base, is the same dark blue color.
The color(s) purple (#66076D), blue (#010173), black (#000000), silver (#C0C0C0), white (#FFFFFF) is/are claimed as a feature of the mark.
