Lavender Brown - help needed

Hello everyone!

I need help. As you probably know HP lexicon has recently updated
bios of minor characters in HP books (Seamus, Rosmerta, Ernie,
Griselda and many others). It was a great read and I highly
reccommend it for everyone. One thing really bugs me:
Lavender Brown's page. Lavender, as shown on the fanart by Marta T
(http://www.hp-lexicon.org/wizards/brown.html), is a white girl
with blond hair, while the actress who played her in the third movie
(Jennifer Smith,
 http://en.wikipedia.org/wiki/Image:Lavender_brown.jpg) is black. I
remember reading an article in Polish press when the first movie
came out, that JK Rowling personally supervised the process of
casting young actors to make sure they all look the way she
imagined her characters (I don't know if she supervised the casting
for third movie). Now I find myself wondering, how Lavender looks
like after all? I cannot recall Lavender's description from the
books since I do not own original English version. I was trying to
find anything myself in my books (Polish version) and I found
nothing. If anyone of you have came across any decent
description of Lavender I would be grateful for your help!
If this issue was already discussed then forgive me for bringing
it up again.

Thanks in advance!
 Rita
