As most of us already know, sunlight is made up of many colors. This fact was discovered by Isaac Newton. Light colors are different with paint colors. Mixture of light colors will produce white light. However, when you mix colors of paint, it will turn darker and darker! So, what's going on actually?

We can see colors of the object because it reflect the specific color and absorb other colors. For example, a red tomato reflects red light and absorb others.

Paints work by soaking up light colors. So, more paints will soak up more lights, which will be darker. Differs with light, more light colors will produce white light.
So, the background of this blog is made up of many light colors, right?
