How to Choose the Color of Paper
Color is the #1 attribute when shopping for paper. And yes, there are many choices beyond White and Ivory. But White and Ivory are the standards for business and personal correspondence with good reason.
White
White is the traditional color for business communications. It’s the best way to display color in its truest form. It’s great for showing contrast.

- Brightness, as specified by the TAPPI is the measurement of the amount of reflectance of blue light (Wavelength 457 nanometers, 44nm wide).

Ivory
Ivory paper has also become a standard in today’s offices. Ivory is “warmer” than white and evokes a feeling of tradition, like something of value that has been handed down through the generations, worthy of preserving.
Neutrals
If you think it’s impossible to be different yet maintain a professional appearance, think again!
There are many different colors which when produced in subtle tones appear to be just as traditional as ivory or white. Gray is just one example of a color that is comfortable in most corporate climates. Think of a law firm … or a gray flannel suit.
But don’t stop there. Southworth also produces a soft and neutral Blue or Almond Résumé Paper that will help job seekers stand out in a sea of white.
