Light\Color\Value

Light:

Something that makes things visible or affords illumination

This is showing different value through light sources from different places. The shapes transform depending on where the light source is hitting the object.

Because there is light, there is also a shadow for each light source. Without light, everything would be black. No color would exist either because color is just the reflection of different light streams into your eyes. 


Color:

Color is the element of art that refers to reflected light. The color wheel is made up of three different types of colors - Primary, Secondary, and Tertiary. The light streams go in the same order of the rainbow, so it goes: Red, orange, yellow, green, blue, indigo, violet/

The primary colors are red, yellow, and blue.  They are called primary for a couple of reasons.  First, no two colors can be mixed to create a primary color. In other words, primary colors can only be created through the use of natural pigments.  Secondly, all other colors found on the color wheel can be created by mixing primary colors together.

Value:

Value deals with the lightness or darkness of a color.  Since we see objects and understand objects because of how dark or light they are, value is incredible important to art. Value deals directly to light.  We see things because light reflects off of objects and goes into our eyes.  Our mind processes the light and rationalizes what we are seeing.  Without light, we cannot see anything. In order to draw or paint in a way that creates an illusion of what we normally see, we must fully understand light and how it reacts on surfaces.  Value is the key to the illusion of light.  This is why value is so incredibly important to drawing and painting.
