Antialiasing is not allowed. You can use dithering.

This is what it says at the bottom of the overview:
“(The same color with different alpha channels is not considered separate colors.)”
Surely that means that anti-aliasing (and for the record, gradients) are allowed since you'd just be using different alpha values for one of the colors to achieve those effects.
I think some further clarification regarding this issue is certainly warranted.

Yes, you are right, I will soon accept a list of rules about this topic. Sorry for the difficulties.
ThePC007 makes sense. Do you agree that the following is a black and white image?
... or would you count each antialiased pixel as a separate color? Antialiasing is a very small amount of pixels used to stop the art from looking like trash, not a way to circumvent the rules. The image is black and white. Also there is no way to replace antialiasing with dithering.
