VALUE

VALUE

Value is everything.

Value is the cake itself while colour is the icing.

Value is the element using  darkness and lightness 

to reveal surface changes.

Value is not colour, everything can have colour but without value it will not look 3-D. One would not be able to tell the difference between a smooth shiny shape and a rough surface.

One can see that this image of a rose does not have any sharp edges, nor does it have glossy shiny surfaces. One can decipher this by observing the gradual change in value. A sudden shift would indicate a sudden surface change and that it is not a rounded surface and may also reveal a sharp edge.

The above image shows four of the five ways to render values in art. The five ways are cross hatching, parallel hatching, scribbling, shading and stippling.
