This web page uses Javascript to convert "regular" numbers used to represent red, green, and blue in Cascading Style Sheets (CSS) color style to and from hexadecimal color codes. The Javascript is from http://www.w3.org/MarkUp/Guide/Style (Dave Raggett's Introduction to CSS)
Here are some colors you can refer to by name (and their hexadecimal codes):
| black = "#000000" | green = "#008000" |
| silver = "#C0C0C0" | lime = "#00FF00" |
| white = "#FFFFFF" | olive = "#808000" |
| gray = "#808080" | yellow = "#FFFF00" |
| maroon = "#800000" | navy = "#000080" |
| red = "#FF0000" | blue = "#0000FF" |
