When we do a logo for a client, we make them brand guidelines as well. For ProVision, we made them a new logo. Once it was finalized, we made the brand guidelines. It covers, all the different ways the logo can be shown, official colors (in many formats, i.e. Pantone, RGB, CMYK), official fonts, minimum clearance rules and general brand representation rules. Brand guidelines are very helpful for creating a more consistent company public image.
