1. Set Design

2. Color
The spectrum are the different forms of radiation that travel all around us. Color is the result of a reflection or absorption of light rays by a given surface. Sunlight passing through a glass prism forms a series of brilliant colors called the spectrum.

3. Hue: the name used to designate a color.
Primary colors: In pigment there are three primary colors: red, blue, and yellow. These cannot be made by mixing but can be combined to form other colors.
Secondary colors: created by blending two primaries.
Triary colors: are a three color blend.
Intermediate colors: are when two neighboring colors are mixed, such as yellow-green, blue-green.
Neutrals: white, grays, and black.

4. Color Harmonies
The relationship is the basis of all color harmony.  There are various ways of combining colors to achieve harmonious effects.
Complementary colors: the use of colors opposite to each other on a color wheel.
Monochromatic harmony: the use of one hue in different values and intensities.
Analogous or neighboring color: the use of a group of neighboring colors adjacent on a color wheel

8. We use art to create a mood of the person viewing the art.
Cool colors: Colors with a predominance of blue. Recede
Warm colors: colors with a predominance of yellow and red. Advance the objects in a painting.
Color Values: the lightness or darkness of a color.
Tints: Values that are lighter than middle value. Tempera tints are made by adding a little color to white. Watercolor tints are made by adding more water to color.
Shades: Values darker than middle value. Tempera and watercolor shades are made by adding a little black to colors.
Intensity: The brightness or dullness of a color. (chroma)
Bright color: pure color at full intensity.
Dull color: A color grayed through the addition of some of its complement(opposites on the color wheel). For example, to dull blue, add its opposite, some orange.

9. Light
Light source: The direction from which the light comes in the pictures.
Highlight: The place on the object that is exposed fully to the light source-where the light hits the object directly.
Halftone: The soft edge of the light where it meets shadow, or a gradual transition from light to dark.
Shadow: The dark area on an artwork where the light is blocked out, just like your own shadow.
Reflected light: The lightened area in a shadow created by light bouncing off another object. This causes portions of the shadow to be lightened slightly.

10. Accent Light: 
Illumination used to make something stand out. It may be done with intensity and/or color.

11. Backlight
Illumination on a subject from behind, causing a separation of the subject from the background, often creating a fringe of light around the subject. 2) A luminaire that provides such illumination.

12. Direct Lighting
Illumination on a subject or area that goes directly from the front of the luminaire in a straight line to the subject or area.

13. Downward illumination, almost perpendicular with the floor
Down Light
Downward illumination, almost perpendicular with the floor

14. Fill Light:
Supplementary illumination used to reduce shadows, preventing them from appearing black. A luminaire that provides such illumination.

15. Gel: gelatine in front of a luminaire to alter the color of the beam.

16. Gobo

17. Spotlight

18. Proportion
Too much variety might be confusing. Sometimes one might want to exaggerate props or set for emphasis at other time one might want to diminish the size.

19. Repetition
Is the repeated use of the art elements to produce rhythm and pattern in design. A picture has unity if all elements are in harmony, if not the picture is in a state of confusion.

20. Emphasis
Is the point of the viewer's focus. The emphasis is determined by the size, color value, and dominance of an object or shape in the artwork.
