The skin color of fish is used to demystify human skin pigmentation. As revealed by studies, a fish skin color is influenced by both genetics and the environment. For example, the skin pigmentation of fish exposed to a more saline environment and fed saltier food is different compared to fish exposed to a lower concentration of salt. Based on years of studying fish skin color, it can be deduced that the variety of human skin pigment is also influenced by genetics plus the environment.

Use the pH color scale. It shows acidity level of both acids and bases. You dip one of the pH strips into whatever liquid you choose, and then compare the new color of the pH strip to the colors on the scale. This will tell you the level of acidity. pH scale can be found below. As you can see, the brighter colors are more acidic than the darker and duller colors.
