I'm a graphic designer and my company is usually very protective of our system mark. All of our centers use the same logo with simple text below to designate the location. We don't allow any alterations to the logo (font, color, layout) for any reason.
However, we are now opening a children's center and now upper management wants to alter the logo just for that department (i.e. add a flower or sun or child-friendly fonts & colors). I'm concerned because I want to preserve the integrity of our logo to keep recognition as high as possible.
What is the right thing to do? Should I allow the alteration, or fight to keep our logo unchanged? And if I should fight, does anyone have convincing arguments to use?
Thanks!
