Basic Materials question

When creating a material you can set the diffuse intensity by adjusting the slider in the diffuse color picker window but there is also an intensity button located directly below in the diffuse settings. If I change the intensity using the color picker slider it does not change the value that appears in the intensity box. What is the difference? What characteristic is being affected by each control? They both appear to do the same thing.


The one below sets the intensity of the color overall. Anything above .8 is not really considered correct as diffuse light from the object will not normally be greater than 80% of the light hitting the object in the first place.
The one in the color picker affects the darkness of the object. If you notice the color you have there, Green can’t get much lower, but red will disproportionately get lower because it is the dominant color.
