Is it really 1-bit if there is an alpha channel?

I don't get the alpha channel exception. Is it really 1-bit (0 or 1) if the alpha channel has like 256 additional values?

1bit (black/white) + 9bit (256 alpha channel) =10bit? [I'm not that knowlagable when it comes to IT, so correct me if I'm wrong.]

I don't want to be rude, just curious.

The alpha channel must be implemented at the engine/code level. This means that all graphics are still 1-bit.

So let's say we use red and green as 2 colours. If we enable the alpha on both of them and overlap each other, they can create any shade of orange or yellow thus technically making a 3rd colour to the naked eye or if you use the colour picker. Is this fine and won't result in disqualifications?

Well, technically it's possible. But I'm not at all sure that such a trick is appreciated by the jam community. This assumption was approved after a vote. You will not be disqualified, but your game may get low scores in the "1-BIT" category.

Thanks for the info. I just wanted to confirm that since people can exploit the theme and there's lot's of confusion regarding the same.

Thanks, I think I get it now.

So no semi-transparent pixels when making sprites. Makes more sence now.
