percentage of S.T.U. student's favorite pet

The pie chart sideway shows the percentage of the student at S.T.U. about their favorite pet. The investigate was taken in 2007 May.
To base on the pie chart we can tell there have about 30% students could like the dog be their pet, about 24% for the cat, about 17% for the rabbit, about 11% for the mouse, and about 18% for others like fish, turtle, snake...etc.
Comparing the different piece of pie chart. The dog is the most popular pet of S.T.U. students, second is cat, third is other, fourth is rabbit, and the last one is mouse. We also can see from the pie chart, there have no too big difference between each one of pet. But still the dog and cat are most common pet people could like to have.

color article

Color is the visual perceptual property corresponding in humans to the categories called red, yellow, white, etc. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.

Color is a visual perceptual ability in humans to the classifications called red, yellow, white etc. Color stem from the spectrum of light (classification of light energy against wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color classifications and physical specifications of color are also related to target, substance, light sources, etc., bottom on their speciality such as light digestion, reaction, or emission spectra.
