Primary Web Color
The University’s primary web color is darker than that used in print to ensure low-vision and color-blind users have adequate color contrast between the font and the background color. This color should be used for headers and branding.

Trademark
The Columbia trademark should be used either on white or dark blue to ensure there is enough color contrast for website accessibility.
