Logo and brand ​

The logo shows the idea the name comes from: a slope cut by a circular slip surface, the mass above it sliding down along it. Each version comes as an SVG, sharp at any size, and as a PNG with a transparent background.

  • Keep the logo as it is: do not recolour it, stretch it, add effects or set the name in another typeface.
  • Use the dark-background version on dark or busy backgrounds, and leave clear space around the logo at least as wide as the IQ badge.
  • Below about 24 px, use the mark on its own; the lettering is no longer legible.
