CA8.Colors
We see the colors everyday and everywhere.We know the colors come from,but do you know who was the first person to study the colors of the world?The first scientist to study color was Sir Isaac Newton.He was an English scientist who lived from 1642 to 1727.Newton was the first person to divide white light into different colors.
In 1861 another English scientist,James Clerk Maxwell,showed that he could make other colors by mixing the primary colors – red,blue and yellow – in different ways to make other colors.These other colors are called secondary and tertiary colors.
We make secondary colors by mixing two primary colors together.For example,red and yellow become orange,yellow and blue become green,and blue and red become violet.We make tertiary colors by mixing one primary color with one secondary color.
We can make a room look bigger or smaller,hotter or colder by using color.Green and blue are cold colors.They can also make a room look bigger,red,orange and yellow are hot colors.They can make a room look small.
