What is a penis rash? There are multiple conditions that can cause a rash on the penis or in the groin. Rashes are commonly itchy and can be caused by something as simple as an irritation to certain soaps or something as complex as an infection caused by fungus, an STD or pubic lice.
Purple on the fixtures and fittings and plaster = very high chlorine stabilizer or conditioner levels. It can also be caused by metals and/or minerals in the water, particularâ¦ly manganese. The manganese reacts to the high level of chlorine (when you shock your pool for example) and turns the water purple.
Rainbows are caused by the splitting of white sunlight into it component colors by raindrops. Some of the light that falls on a water drop enters the drop. As it enters the drop, the color components of the sunlight are refracted (bent) by different amounts depending upon their wavelength (we perceive the different wavelengths as different colors.)
