Color can be a vital indicator of a lot of things. In medicine, often, any kind of deviation from the ordinary is reflected by a change in color. For example, in jaundice, often the white of the eye appears yellowish. Thus, its essential that we always keep an eye out for any kind of change in the color of normal structures or excretions, and thus, urine is no exception to this rule. Urine color change is a vital indicator of an underlying disease and disorder. Thus, urine color meaning is a very important sign, which could help in identifying a disease at the earliest possible stage.
The kidneys, are the organs responsible for producing urine. Both the kidneys are continuously involved with filtration of blood. The kidneys process blood plasma, allowing water, sugar, amino acids, vitamins and other vital substances to re-enter the blood stream. The continuous filtration eventually sorts out waste substances like urea, uric acid, creatinine, hormone waste and toxins, and excretes it in the urine. The normal color of urine is pale yellow, and this color is due to the pigment urochrome. However, this pale color of urine is sometimes altered when, in cases of kidney diseases, the filtration and selective re-absorption stages of urine production are faulty. Due to this, certain elements, like red blood cells, white blood cells, proteins, dyes, etc. also get filtered through, thus passing into urine. This leads to a change in urine color, which is often indicative of the exact malfunctioning level of urine production. It's this meaning of urine color that is used to reach a temporary diagnosis. Given below are different urine colors and urine color meanings.

So now we know all about urine color and what it means, and although urine color meanings are significant, and aid in giving us an idea of the underlying disease, one should not solely rely on the urine color for reaching a diagnosis. A final diagnosis should only be made after lab tests have been done regarding that disease, like a microscopic urine examination to look out for protein in cases of urinary tract infections, etc. Thus, urine color meanings often act as a stepping stone towards a final diagnosis of a disease or condition.
