Writing the set-builder form:

Given set,

Set of colours of a rainbow.

In Set Builder form, the set is described by stating a condition or property which an object or element must satisfy if it belongs to that set.

$S=\{x|x\mathrm{is}\mathrm{a}\mathrm{colour}\mathrm{in}\mathrm{rainbow}\}$

Thus, the given set in Set Builder form can be written as $S=\{x|x\mathrm{is}\mathrm{a}\mathrm{colour}\mathrm{in}\mathrm{rainbow}\}$
