Antialiasing creates grey pixels, so is it allowed? This question goes for both 3D (automatic AA) and 2D (manually drawn AA).
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.
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.
