eye colour and other queries

[Sharon]

Hi all,

I posted on the main HP list about eye colour and then thought it might be a bit off 
topic--or could easily GET off topic.

basically, I've been reading a lot of fanfiction and am curious about some things that seem 
to be common to a lot of fics but i don't remember from canon.  If anyone can tell me 
whether they are in canon I would be SOOOOO happy.  Here they are:

1.  Harry's eye colour is always described as a deep green (or jade or emerald etc). I 
remember them being described as 'green' but where did this unusual 'absinthe in flames' 
kind of colour come from?  That doesn't even seem like a 'real' eye colour to me.

2. Draco's eyes are always descibed as grey (my favourite is 'full-moon-over-the-water' 
LOL). I don't remember Draco's eyes ever being described in canon at all, though I possibly 
wasn't paying attention.

3. Many of the fics talk about 'glamour spells'--are they fanfic-created or in canon?  I 
cannot remember ever reading about a glamour spell.. though they sounds like a brilliant 
idea of course.s

4. They also talk about 'wards' being around premises -- kind of like protective spells to 
keep others out.  I KNOW there are such spells in canon but where are they described as 
'wards'?

If anyone can point me to a relevant passages or chapters I would be so grateful. I've read 
the books SO many times over and can't beleive I've missed these if they ARE in fact, there.  
It's driving me crazy!!!!! LOL  And I thought rather than starting from book 1 again i would 
put it out there in case anyone knows.....

Thanks,
Sharon
