brown

Brown is a composite color. In the CMYK color model used in printing or painting, brown is made by combining red, blue, and yellow. In the RGB color model used to project colors onto television screens and computer monitors, brown is made by combining red and green, in specific proportions. In painting, brown is generally made by adding black to orange or yellow.
The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty. More positive associations include baking, warmth, wildlife, and the autumn.

    Brown sludge/scum floating in CH header tank, is this just bacteria ?

    I was about to drain the heating system and noticed a brown skin floating on the top of the water in the header tank. there is also some white 'salt like' colouring. I assume this 'scum' is a sort of bacteria that needs to be removed before draining the system. Can anyone advise what it is please?
