I am looking for the meaning of the expression, "liquid browns" when
used in reference to someones eyes.  The origin of the expression
would be of interest as well, but not necessary.

Someone told me the other day that I have liquid browns, only I had no
idea what the heck he was talking about.  After noticing my dumb
expression, he said he was talking about my eyes, and said to think
about it.  Now I have some idea what it could mean, but I have never
heard the expression before, so don't really know.  I am assuming he
was flirting with me, but who knows.....

Hi arcookie,

I hope you are a dog person!

Webster's 1913 Dictionary: Liquid: adj.
Clear and shining: the liquid brown eyes of a spaniel.

The FreeDictionary.com: Liquid: adj:
Yielding; lacking any hint of hardness; ... "the liquid brown eyes of a spaniel"
Related Word: Soft:  ...metaphorically soft; "a soft rain"; ..."soft
brown eyes"; "a soft glance"

There you have it, *soft, clear and shining* - lucky you.  I'm sorry I
couldn't find when the phrase was first used, but you know it was in
use as early as 1913. Your question reminded me of some tips I read
many years ago which included advice to pinch your cheeks to produce a
natural blush and to put eye drops in your eyes to make them bright
and soft (and to remove any redness). If you have any questions,
please post a clarification request *before* closing/rating my answer
and I'll be happy to reply.

Thank you,

Thank you so much for your thorough response.  I don't know why I
couldn't find this one myself, but I was thrilled to accidentally find
out that Google offered this service, and thrilled with the results. 
Well worth the money paid so that I could get back to work and stop
google searching on the job.

Arcookie, thank you for your nice note, rating, and tip - I appreciate
them all. Take care of those eyes of yours (don't stare at the monitor
for too long), it sounds as though they are a real asset. Sincerely,
hummer
