Exercise 5-1

1. Hands-On Exercise
1. RGB code: 23, 200, 159 converted to Hexadecimal is 17C89F.
2. Hexadecimal code C70B48 converted to RGB is 199, 11, 72.


2. Extra Review Questions
1. List the complete names and file extensions used for the
   three image file formats used in Web pages.
1. GIF (Graphic Interchange Format)
2. PNG ( Portable Network Graphics)
3. JPEG (Joint Photographic Experts Group)


2. Of the three formats, which offers the best color display?
   which may not be supported by all browsers?
1. JPEG produces the most true colors.
2. PNG may not be supported by all browsers.


3. From this topic, list at least 5 design issues that you
   should begin to consider as you add color and graphics to
   your pages.
1. Make sure that your background is not so "busy"
   that your text is hard to read.
2. If tiling an image make sure to choose something
   that does not have an obvious boundary.
3. Remember that the average home computer user is connecting
   via a dial up modem and do all possible to make your pages
   load faster (ie always code the dimensions of images, use
   interlaced GIF's etc).
4. Use web safe colors to ensure that your website is viewed
   more consistently on different browsers
5. Don't break the law - you can't just copy any image from the
   internet and use it. Look for sites that specifically state
   that you may use their images or ask permission otherwise.
