Maybe for a 3-year old child. Doves can count to 7. Earthworms may
fail at 1 already.

Many animals can differentiate quantities up to about 7. As far as
we know most of them needn't and can't count. They just see the
difference. Accurate determination of larger quantities may require
counting.

None of which is relevant to may observation that if n = 5 then your

If you have no idea of 6, it is dark for you. I you arbitrarily stop at 5 although you know 6, 5 is not dark for you.

 I do have an idea on numbers greated than n. But per OP they are dark
anyway.

If you can express them so that a reader can recognize them, then they are not / no longer dark.
