Introduction:
For as long as painters have made their visions and dreams into images, they have relied on technical knowledge and skill to supply their materials. This is a little known fact among the general population as well as artists due to the easy accessibility of paint and paint supplies. However, only a few centuries ago artists were generally very involved with the paint-making process, and had to carefully choose their ingredients, or else the color might fade or go bad once it was on its canvas. In short, chemistry was laid out on the artist 's palette. This paper explores the processes of creating color, it 's relation to chemistry, and how art and chemistry are involved in everyday life.

The frequency of their vibrations determines the color of the light, which increases progressively from the red to the blue end of the visible spectrum. As frequency increases, the wavelength declines.
At the beginning of the twentieth century, this picture was refined even further with the realization that, as the quantum theory proposes, light is not just a wave but a particle as well. Light comes in quanta, or photons, each containing a certain amount of energy proportional to the frequency. A substance 's color is generated by absorption of light; this process is governed by the material 's resonant frequencies. Just as an undamped piano wire might hum in sympathy with a sung note, matter "sings" along with sunlight. The resonant vibration absorbs the energy of the light at that frequency, thus stripping out a particular color from the spectrum of light. Rays whose frequencies don 't correspond to some resonant frequency of the material either pass through it or are reflected; these rejected rays are the ones that reach our …show more content…
