Friday December 24, 2004 | What color do you see? | Computers |
When is grey not grey? When you're viewing it with Internet Explorer, that's when.
The following words should match their color: blue red gray green grey
With most browsers, the word "grey" is the color grey. But when viewed with Internet Explorer on XP, I see it colored green! You might assume that the parser sees "gre" and assumes "green" but the color displayed is a lighter shade of green that what is displayed for the the word "green" (did that make sense?).
The following code was used to display the colored words above:
<font color="blue">blue</font> <font color="red">red</font> <font color="gray">gray</font> <font color="green">green</font> <font color="grey">grey</font>
I'd be interested in hearing people's explanation for this. I did find
this link that
describes the same behavior, but doesn't offer any insight.

And why, pray, are you using IE instead of FF ;)

I am using Firefox! But as a good web developer, I test on other browsers.
Bummer! A month ago I put up a simple website with three nice shades of grey. Unfortunately, for the darkest grey I didn't use color codes, but the word "grey".... and today it turned out that all IE users have been seeing it in glorious shining green. Nice! Err...
Okay, I learned a lesson and will check even simple pages with several browsers.

But here's an interesting link from seven years ago!
A quick test shows that many obscure names for both existing and non-existing color names are translated similarly by Mozilla and IE, but also there are several different interpretations.
Go figure!

That is both funny and scary. I have to assume that there is a hash table of color names to color codes and that there is more than one way to reach each color code.
IE tries to interpret unknown colour names as a RRGGBB hexidecimal number, treating all non-hexidecimal digits as zero. It then seems to pad with extra zeros to get six digits.
So "grey" => 00e0 => 00e000
=> red=0, green=E0=16*14=224/255, blue=0
=> green!
