What two prime numbers are successive?

The two successive prime numbers are 2 and 3. 1 is not a prime number because it has only one factor, while prime numbers have two positive integer factors.

What are similarities between prime numbers and prime colors?

Prime numbers and prime colors are both fundamental in their respective fields. Prime numbers are integers greater than 1 that are only divisible by 1 and themselves, while prime colors are pure and cannot be created by mixing other colors. Both prime numbers and prime colors are considered basic building blocks in mathematics and color theory, respectively. Additionally, just as prime numbers play a crucial role in number theory, prime colors are essential in fields such as art, design, and psychology.
