Visual Notes

Colors

The official Northwestern purple hexadecimal code for web pages is #4E2A84.

Web-safe Colors

Web-safe colors are not required for two reasons: 1) a minuscule percentage of users still use 8-bit monitors; and 2) a simple workaround exists: Use transparent backgrounds for images. Web-safe colors were advocated in the past because older monitors were only capable of displaying 256 colors.

Graphics and Photography

GIF, PNG, JPG, and SVG are the most common formats for web graphics.
