At the simplest level it was the Bohr model.
cathode ray
In flame tests, atoms or ions are excited to higher energy states by the heat of the flame. When they return to their ground state, they emit photons of light in certain wavelengths, which correspond to specific colors. Different elements or ions have unique electronic configurations, leading to specific energy level transitions and hence, different colors observed in flame tests.
Objects look certain colors because they reflect and absorb particular wavelengths of light. The color we perceive is the result of the wavelengths that are reflected back to our eyes. For example, an object appears red because it reflects red light waves and absorbs other colors.
The name of the range of colors emitted by a heated (energized, excited, etc...) atom is called an emission spectrum.
Metals such as sodium, potassium, calcium, and copper can be excited using a Bunsen burner flame to emit characteristic colors. This technique is commonly used in flame tests to identify different elements based on the color of light they emit when heated.
name that element that explains how symbols and colors relate to the data
all the colors
Cool colors(blue, green , and violet

Not sure exactly what this question refers to, but it may be asking about the atomic emission spectra where each element of the Periodic Table emits certain colors of light when excited.

put a answrer
I'm pretty sure that is is color blindness to certain colors which makes it so you can only see certain colors.
Hydrogen and ice
Bohr's theory helped explain why electrons orbit the nucleus in specific energy levels, rather than spiraling inward towards the nucleus due to electromagnetic forces. This theory also provided a framework for understanding the discrete emission and absorption of energy by atoms in the form of photons.
When electrical currents re passed through certain gasses (not glasses) the molecules become excited, and give off photons. The color depends on the gas used.
