The grayscale version of the AvantGo logo maybe used when the color reproduction of the logo is not possible. The gray is a 40% black tint. The grayscale logo may only be used on white background, except when displayed on a 4 bit color device. The grayscale logos have the same proportion as the color ones. There are master art versions and specially adjusted versions of the grayscale logo for scaling purposes. Consult the Scaling section for more detail.
