Is Q3 d wrong because part of the overalls MUST be yellow, while e is correct because the overalls COULD have violet (or red)?

D is incorrect due to it being the case that the overalls cannot be at least in part yellow.

If any part of the jacket is green, what do we know?

Consider if the jacket could be green as one single color. It could not, right? You then would be unable to have a color in common with the overalls, as green is not a color available for the overalls.

So we now know that for the jacket to be in part green, that it has to be plaid, which triggers the concept of it having all three colors used.

J: G R V

This now means, according to the rules, that the overalls must be a single color. We have 3 colors to choose from: Y R V

J: G R V

O: R/V

The overalls could either be entirely red or entirely violet. It could not be yellow as then it would not have a color in common with the plaid jacket.

Why can't J also have the possibility of two colors and not just one or three...why can't J be gv and O has V so V is in common?

The first rule is prohibiting what you're describing.

The jacket/overalls have to either be solid (1 color) or plaid (more than 1 color).

BUT, the first two rules specifically require that when the jacket is more than 1 color, it is exactly 3 colors.

(When the overalls are more than 1, they are exactly 2 colors).

So it would break rule 1 to ever have the jacket with exactly 2 colors.

Does that make sense?

Hello,
Thank you for reaching out!!

I do get the overall rule that 2 is the max.
When you said:
(When the overalls are more than 1, they are exactly 2 colors).

But I still think that the Jacket could be two colors, and not just 1 or three. There is the exception that if the overall is 2 colors then that makes the jacket be one color and has to be either red or violet to have a common color with overall. Green in this case is out.

To me the rule does say this:
The jacket/overalls have to either be solid (1 color) or plaid (more than 1 color).
But if the jacket supposedly is plaid then, it can be green and (violet or red), or violet and (red or green), or red and (violet or green). And this would make the overall be have either red or violet in common not both and option of yellow.

So my question is where do you get this inference when you say"
BUT, the first two rules specifically require that when the jacket is more than 1 color, it is exactly 3 colors."


This is why I took forever to finish this game and get it wrong.
