sure that the image is really black there? (0/0/0)

yep it is i checked 0,0,0
How are you viewing the result?
Is it in the opengl viewport or rendered output?

yer in both. It renders particles in places of black but in the white it renders a lot more...

where did you make the image? maya or photoshop.
if you made it in maya there might of been some spec or a light giving a extra pixel of white to the black.
try remaking the image again in Photoshop or double checking you pic.
Use Levels in Photoshop to constrast the image more, just to be sure everything is pure black.

Can you post a screenshot? Or post the scene and texture?
Maybe it has something to do with the UV mapping....

i have checked now with several procedural and painted files and was not able to reproduce that..
just to check: did you save the file you use as .jpg maybe?

Yer its was because it was a .jpeg but why would a jpeg do that ? cant jpegs save 100% black? it doesnt say anything about not using jpegs in the docs???

honestly that was just guessing, that the compressen screws up color values in some points..
that could (and can as we see) lead to pixels that are quite close to but not really are black ;)
