Opening a business is kind of like planning a wedding.  For instance, you have to pick a color scheme and stick with it.  And I'm only using this as a reference because I just planned my own wedding.  And it was all about colors.  Choosing colors for the wedding didn't seem so hard compared to deciding on the colors that the cupcake shop will represent.  It goes in the paint, on the logo, in the packaging, on the sign, website, menus, all the advertising, even the chandeliers!  For the most part, it's the colors that represent what feeling you're trying to evoke.  Fun, Shabby Chic, French, Modern...these are usually themes that are established with colors! That is a lot for one little color choice (or 3, or 4) to represent.
