Instead of asking what is the opposite, why don"t you ask a different question?

You tend to look at the world in black and white terms. This or the opposite...

But often what you think is the opposite is not...

My current favorite book, 46 rules of Genius, says:
"Rule 24 (of Genius)

"SIMPLIFY
"People tend to view simplicity and complexity as opposites. But this isn"t strictly true. The enemy of simplicity isn"t complexity, but disorder. And the enemy of complexity is also disorder. While complexity seeks order through addition, simplicity seeks it through subtraction.
"A goal of design is to drive out disorder by maximizing both simplicity and complexity. In most designed products, what we respond to best is a rich, layered experience (complexity) combined with ease of use, ease of understanding, or ease of purchase (simplicity).
"Most people have a built-in bias toward addition instead of subtraction. For some reason, the concept of “more” comes naturally to us. Yet the innovator knows that the value of any design doesn"t lie in how much is piled on, but how much is discarded. More is more, but less is better.
