#### 22.7.2 Using Web-safe colors

It is best to use Web-safe colors for HTML; otherwise you could run into browser palette issues.

For Web-safe colors that are rendered the same by all browsers, use color numbers 1 through 8, or define colors with elements of 00, 33, 66, 99, CC, or FF For example, RGB hexadecimal value 0099CC yields the color shown in Figure 22-1.
