Why are some primary colors called additive?
If you are mixing colours, you have to be clear if you are mixing lights or pigments/paints. If you are mixing lights, you get more light, so this is called additive mixing of colour. You do this by shining different coloured lights on to a screen.You need blue, green, and red light to make white light. Red, green and blue are the additive primary colours because none of them can be made by mixing other colours. If you are mixing paints, this is subtractive, because paints work by absorbing light, so if you have more than one, more light is absorbed and less is reflected to the eye. The idea of the subtractive primary colours of red, yellow and blue is used in art rather than science. In science we would define them as cyan, magenta and yellow.
Distinguish between additive and subtractive color mixing processes?
The additive color process is mixing lights while the subtractive color process is mixing paints and dyes. In the additive color process when you mix all of the main colors together: red, green, and blue: you get white(hence the name additive) while if you do the exact same thing in the subtractive color process: cyan, magenta, and yellow: you get black(hence the name subtractive because in order to get white you'd have to take away all of the colors).
An intersection with no lights or signs is called what?
Uncontrolled intersection
