There is no evidence Adam and Eve were not happy being subservient to God. God had been so good to them. He walked with them in the garden in the cool of the evening. They had all they needed in the garden. Eve was seduced by the color and aroma of the fruit and the words of Satan “That ye shall not die” and would make her wise. This was trickery. Lies from Satan meant to flatter and deceive.
Genesis 3:6 ESV
So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise, she took of its fruit and ate, and she also gave some to her husband who was with her, and he ate.
Sorry - no mention of 'color' or 'aroma'.
