E-Man's Sprite R & D

[E-Man]

That's a good question! You see, I purposely avoid using pure white (Hex #FFFFFF) and pure black (Hex #000000) because that's a rookie mistake. Not only are they glaringly noticeable, but some applications (MS Paint is a good example) cause strange things to happen to its transparency when used.

In short, if you must use black or white, then use values that are close to it, but are a little impure to avoid technical and visual problems. Since a lot of other good pixel artists keep this information under their hat, I'm sure I'm not alone with this preference.
