A single LED emits light at one single frequency, so it has no spectrum.
Different atoms have a different number of electrons. This is why they show different spectra.

Stellar spectra are graphs or visual representations of the intensity of light emitted by a star at different wavelengths. They provide information about the star's temperature, chemical composition, and motion towards or away from Earth. Studying stellar spectra is crucial for understanding the properties and evolution of stars.
The spectra of the stars you want to analyze.
Every color has a different frequency. That's why it appears to our eyes as a different color.
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
Different atoms have a different number of electrons. This is why they show different spectra.
The color of your poi may depend on the type of fabric or material used, the lighting conditions, and the color of the LED light inside. Try changing the LED light color or using a different fabric to achieve a purple color.

They have different packaged particles.
The Kia Spectra comes in gray, black and beige interior colors. Carsdirect.com offers a combination color key here, http://www.carsdirect.com/kia/spectra/colors.
A normal incandescent or fluorescent lamps can not change colors. Even an LED can not change color. But an LED can be designed to have a certain color. Color changing LED is actually a combination of of three LEDs encapsulated in one casing. By turning the LED on or off a combination of colors can be achieved.
It is called Visible light Spectrum.

The different types of spectra are created by light shining through a prism, a glowing solid or liquid, or by a compressed/non-compressed glowing glass.
The nucleus of an atom does not directly affect the atomic spectra of different elements. The atomic spectra are mainly a result of the electron configuration and transitions in the electron energy levels. However, the nucleus can indirectly influence the spectra through its impact on the arrangement and energy levels of the electrons.
