The different colored petals of a flower are called "corolla."
Usually the petals are the colorfal/attractive part of a flower.
The collective name for the petals of a flower is the corolla.
In most plants, this would be the flower; specifically, the petals.
Together, the petals of a flower are called a corolla. Also, the sepals as a group are called the calyx, and the corolla and the calyx together are called the perianth.
Petals are usually surrounded by sepals, which are usually photosynthetic (green) and support the petals from underneath. They may be slightly smaller than the petals, tiny, or even apparently absent; occasionally they may be larger and showier than the true flower petals.

The structures you are describing are called sepals. Sepals are typically green and leaf-like, forming the outer part of the flower bud and encircling the base of the flower stem beneath the petals. They protect the flower before it blooms and can sometimes provide additional support for the petals. Together with the petals, they make up the flower's non-reproductive parts.

An orchid flower typically has three sepals. These sepals are often colorful and can resemble petals, contributing to the flower's overall appearance. In addition to the sepals, orchids also have three petals, one of which is usually modified into a distinct structure called the lip or labellum.
Papaya flowers typically have five petals. The petals are usually white and are arranged in a star shape.
