Hanabi difficulties

[Izor Oak]

I understand the difference between normal and tricky, with tricky just adding a sixth suit. But I dont understand the differences to difficult and very difficult. I played a difficult which states 6th color (5 cards) but it felt identical to the tricky one. Can someone care to explain?

Difficult includes only 1 of each number for the 6th color. (so there are no duplicates in this color, making it extra important to avoid throwing any cards of this type away).

Very difficult includes the usual 10 cards for the 6th color, but you cannot give the multi-color clue directly. Whenever a color clue is given, the multi-color clue is positive for that color. So if you gave a blue clue all blue and all multi-color cards are noted as blue. Later if you give a yellow clue all yellow and multi-color clues are indicated...at which point you would know a card that is both blue and yellow is multi-color.

That makes it all more clear! Thank you!
