different compounds give different emission colors because of the energy level of there electrons when they form. all visible emissions are directly related to the energy levels of the electron. the more energy an electron gives of in the forming of the compound the more visible the emission will be. the lowest being red and the highest being violet.
the colors which we can see are called visible colors that appear in visible light spectrum VIBGYOR these are the only visible colors although we can see different colors by the combination of these colors also whit is a visible color
All kinds of waves, including light, have different possible wavelengths and frequencies. What particular wavelength a light wave might have depends on how it was made. Now if two light rays with different wavelengths enter your eye can you tell there were two different wavelengths? The answer is yes, and the way you tell is that your brain reacts differently to the two waves. The way it reacts differently is by giving the two waves "color". So its not really the waves that have different colors its the way your brain interprets the different wavelengths.
The number of different visible colors is subjective and depends on how the human eye perceives and categorizes colors. In general, the human eye can distinguish around 10 million different colors. This includes all the hues, shades, and tones that make up the visible spectrum.
The primary colors of visible light are red, green, and blue. By combining these colors in different intensities, we can create all other colors that we can see.
A prism can form a visible spectrum by refracting light as it passes through the prism. The different colors of light have different wavelengths, causing them to bend at different angles when passing through the prism. This separation of colors creates the visible spectrum.
You can add colors to fireworks by incorporating specific chemical compounds into the fireworks mixture. Each compound produces a different color when ignited. For example, strontium compounds produce red colors, copper compounds produce blue colors, and barium compounds produce green colors. By using a combination of these compounds at the right ratios, you can create a colorful fireworks display.
colors
Visible light includes all the colors of the rainbow. The different colors are the result of different wavelengths.
Different frequencies of visible light are perceived as different colors.
At different stages in their life cycles they have different temperatures and radiate different visible wavelengths.
...colors when the light enters your eyes.
Humans can see different wavelengths of light as different colors. Shorter wavelengths appear as violet and blue, while longer wavelengths appear as red and orange. The entire spectrum of visible light includes colors from red to violet.
