Web Safe is deprecated. Don't ask me why it's still around. Web Safe was for color displays that only supported 256 palette entry.

Answer 34

If you check out http://marketshare.hitslink.com/ It's surprising how much old hardware is still out there.

Answer 35

FWIW, in my opinion that test seems pretty far out of date. If this is for a class you're taking, you should ask for your money back :p. Otherwise, you may want a better resource. It lists Netscape as a common web browser...

Answer 36

Thats valid........

Answer 37

Okay, I asked about this today and got an answer... it's invalid because the 'web-safe' ONLY contains: 0,3,6,9 and C,F
