◆Constraint: Things not allowed
If you put "anything other than white is not allowed (=negation)" inside the "Things not allowed" frame (negative frame), there is an extremely high risk that the AI will judge it as "not allowing things that are not allowed (double negative)" and consequently misunderstand it as "anything other than white is also OK (affirmation)".To ensure your instructions to the AI are followed reliably, the correct approach is to write only "specific prohibited actions/states" directly within the "Things not allowed" frame.Please try writing it as follows.
English description for "Constraint: Things not allowed" (Revised version)
The AI will recognize that the items in this list are "things you must not do."
Restrictions: Not Allowed
Using red or pink on the face. (顔に赤やピンクを使うこと)
Deviating from the pure white facial color. (純白の顔色から外れること)
Any color bleeding into the white face area. (顔の白い領域に他の色が混ざること)
Resembling a standard red-faced Lovebird. (標準的な「顔の赤いコザクラインコ」に似せること)Key point:
• Do not write "Do not allow anything other than white": As you pointed out, if you write "do not allow making anything other than white not allowed," the AI's logic circuit will become confused.
• Do not allow "using red": This is the way to write it with the fewest errors, by putting "specific states you do not want (a red face)" into the "Not allowed list."
Also, what should be written in the "Detailed Settings (Positive Prompt)":
While strengthening the guard with "Things not allowed," write this in the main description field.
Face color: Always maintain pure white.
（顔の色：常に純白を維持すること）With this, you create a state where **"(in the main prompt) it is told to be white" and "(in the constraints) it is told that red is not allowed,"** which avoids the confusion of double negatives and allows you to protect Cha-chan's pure white face.
This way, the AI will not get lost and will decide "White is the only choice!"
