The logo should be easy to read (even at distance from passing cars), minimalistic, modern, flat, and remember able. The logo should be able to be laid out on one line or have the text wrapped to make it more compact. The font should be a San Serif type and the font can be all or mixture of upper & lower case letters.
In the attached, example the keyhole shape incorporated into a letter is not required consider it optional. I have also attached logos from other national self-storage brands.
The colors used by Storage West, Ocean Storage, and Rightspace (see attached) are probably my favorite, but open to suggestions in the blue, aqua, or green pallets. I do not care for the combination of two bright colors together. Ideally the logo should be able to be placed on dark or light backgrounds.
The use of a padlock, self-storage cube or roll-up door in the logo should be avoided, as these features feel dated.
