Look for the thinking head to help you identify the "big ideas" to take away from the lesson, as well as the open book to easily find definitions.
Value (sometimes called tone) refers to the "lightness" or "darkness" of a colour.
Value is created by seeing light and shadow on an object. When a light source shines on an object it creates what we call "highlights" and "shadows". It also illuminates the local or actual colour of the subject.
Within a work of art, value is the range of lightness and darkness within a picture. Transitions in value can be gradual or sudden.
Gradual transitions
Gradual transitions of value create a more natural or realistic looking shaded image. The artist works hard to create all of the little in-between "steps" in VALUE from lightest to darkest.

Sudden transitions (or changes)
Sudden transitions (or "changes") in value look more extreme and stylized; they can be dramatic and moody because they emphasize harsh changes in light and dark values.

Value can also suggest volume and space.
Value creates depth within a picture making an object look three-dimensional with highlights and cast shadows, or in a landscape where it gets lighter in value as it recedes to the background giving the illusion of depth.
The tonal values of an artwork can be adjusted to alter its expressive character.
Tint is adding white to a color paint to create lighter values such as light blue or pink.
Shade is adding black to a paint color to create dark values such as dark blue or dark red.
High-Key is a picture with all light values.
Low-Key is a picture with all dark values.
Value Contrast is light values placed next to dark values to create contrast or strong differences.
Value Scale is a scale that shows the gradual change in value from its lightest value, (white) to its darkest value (black)
Sketchbook Assignment: Create a 5 value, Value Scale
Create a 5 value, Value Scale.
Beginning with the box (below) on the right, leave it blank. That box will be the lightest value of the value scale. The box on the far left will be the darkest value, so shade it in completely black. The three remaining boxes are then shaded in to show a gradual change from the lightest to the darkest values.
Sketchbook Assignment: Tint and Shade Atmospheric Landscapes
You will be creating an atmospheric landscape painting that uses SHAPE and VALUE.
Research - find 3 images of landscapes (either photography or paintings or drawings)
Use one of these examples as a reference point -- and plan your own "real" or "imaginary" landscape (eg., hills, mountains, vegetation, buildings, sky) as a small pencil sketch that has a FOREGROUND, MID-GROUND, an BACKGROUND
Create a 8 inches wide by 10 inches tall rectangle in the centre of your sketchbook page
Choose a colour that will be you "HUE" and re-draw the outlines of your landscape and the features in it using a pencil crayon that matches your chosen paint hue (eg., if you will paint a red monochromatic landscape then draw the outlines in a red pencil crayon)
You will be creating TINTS, and SHADES to create a transition in value. The FOREGROUND should be painted mostly in SHADES (your hue + black); the MID-GROUND will mostly be painted in your pure HUE; the BACKGROUND should then be painted as TINTS (your hue + white).
Any areas in between the SHADES, HUE, TINT should be created as "half steps" so that the transition in value is gradual an not sudden. (see examples)
