Chapter 17: Saving and Editing Street Maps283Here are some of the most important rules when it comes to dealing with color: Use the same general color scheme as the Web map you’re editing.Any text or features that you add to the map should be the same coloras the text and features shown on the Web map. Use contrast between background and text.• On a light background, use dark text. Black text is usually best.• On a dark background, use light text. Use bright colors to draw attention to a feature such as a location orroute of travel.Use red to identify a location the user is searching for.FontsText labels play an important role in maps; here are some well-founded guidelinesfor using fonts and typeface styles with maps. These tips will make yourdigital maps easy on the eyes: When adding new labels, use the same typeface as Web map text(or as close to the typeface as possible). Feature names should be in a normal typeface. Don’t bold oritalicize them. Feature names should only have the first letter capitalized.Capitalizing an entire name on a map makes it harder to read. Text in a straight line is easier to read and find than curved text(such as a street name that curves around a corner). Sans serif fonts are easier to scan on a computer screen.You’re reading a serif font right now. Sans serif fonts, such as Arial,have letters without serifs (small lines on the top and bottom of somecharacters).If you must use a serif font, Georgia is more legible than Times NewRoman. Don’t mix fonts and font size when labeling map features unless youhave a really good reason.Adding symbolsSymbols convey information without using words. For example, a tent meansa campground, a skier indicates a ski trail, and an airplane means an airport.
