Rashes are abnormal changes in skin color or texture that usually result from skin inflammation, which can have numerous causes.
Rashes can be itchy and painful, and they often look different on various skin colours. They are commonly said to be red, but on darker skin tones, they might be purple, grey, or white.

Some examples of rashes are eczema, granuloma annulare, lichen planus, and pityriasis rosea.
