Too true. Unlike us humans, tarantulas are colorblind (i think).

hahaha i wanna try that now
Tarantulas don't react to colors, since they cannot sense/see colors. Maybe it was the textil the sweater was made from, or some other thing that scared it.
To add some "racist" part. Black people don't like tarantulas? Does any of you here know Thompson08? Seanbond?

I would certainly agree that in this case, the differences in texture, possibly light reflectance, and maybe other physical characteristics probably caused the observed reaction.
I still want to know the evolutionary significance (if any!) of T colors! Anybody know of any hypotheses in this area?

i personally don't think t's can see color. true, arboreals can supposedly see somewhat better than terrestrials, but that isn't saying too much!
but what if they could? what if you had a versicolor that hated the color red? wouldn't it try to bite itself, or run around endlessly trying to get away from the color? jk'ing

jk'inghttp://www.bio.georgiasouthern.edu/bio-home/Harvey/OxfordGillespie1998.pdf feel free to read 25 pages x)) i'm interested too so if someone reads it, resume it on me plz =)) tkz in advanceI would certainly agree that in this case, the differences in texture, possibly light reflectance, and maybe other physical characteristics probably caused the observed reaction.

Tarantulas do probably see colors (sort of).
From studies of the light reactive molecules in the eyes of spiders (opsins), it appears that tarantuals have green/blue vision at least.

They don't respond to red light nearly as well as blue (50-100X worse by opsin absorption) and some may even be blind to far red (~650nm).
Spiders in general do have color vision particularly jumping spiders.

Other nocturnal spiders have poly chromatic vision.

The race thing is no big fuss.
1-In general, mostly urban people like exotics. Rural folks, whatever the colour, don't understand the interest in it, especially that lots of exotics are actually a phobia for many. Those are very conservative, so not disliking animals disliked by most is fringe behaviour to them. Major urban centers in every continent arbour exotics lovers, but Europe has a longer tradition.
2-Many ethnic people thinks that westerners are nuts for giving names to animals, training doctors to pamper them, and spending anything on something that won't give you meat or wool. In some countries, having an affectionate bond with an animal is a sign of weakness or immaturity. It's food or useful in another matter, that's it. Then those folks migrate in the US and witness their neighbours bursting into tears because their cat dies. What is commonly accepted here is infantile there. If they are that reluctant toward cats and dogs, it's normal that they will have even less interest in tarantulas.
And I know all of the above from my coloured students. To them, only humans matter.
