HSV Color Model
HSV Color Model
A color model that describes colors based on three aspects: hue, saturation, and value.
Hue
Hue
The dominant wavelength of a color, giving it its unique name (e.g., red, blue, yellow).
Saturation
Saturation
The intensity or purity of a color. High saturation means a strong, vivid color, while low saturation means a more muted or grayed color.
Value

Study Notes
Color in Production
- Color theory involves the interaction of light, the object, and the observer
- Light illuminates the object, which reflects light to the observer
- The observer perceives the reflected light as color
Additive Color
- White light is formed by mixing red, green, and blue light
- Adding these colors together creates white light
- This is known as additive color
Subtractive Color
- Objects that don't emit light obtain color from the pigments they contain
- The three primary pigment colors are cyan, magenta, and yellow
- Combining these pigments subtracts reflected light, resulting in black
RGB Color Model
- A color model based on additive color mixing of red, green, and blue light
- Used in devices like TVs, monitors, and projectors
- Color intensity is measured on a scale of 0 to 255
- White is represented by (255, 255, 255)
CMYK Color Model
- A subtractive color model used in color printing
- The primary colors are cyan, magenta, yellow, and black
- Combining these pigments produces a full-color image
- Black is often added as a separate "key" color (K) to improve the intensity and reduce color problems
HSV (Hue, Saturation, Value)
- A perceptual color model based on hue, saturation, and value
- Hue corresponds to the dominant wavelength of a color (e.g., red, blue, yellow)
- Saturation represents the purity of the color
- Value (brightness) represents the percentage of reflected light
Color Separations
- Traditional technique for separating full-color art into halftone negatives (cyan, magenta, yellow, and black)
- Used in commercial printing
- Computer-based illustration software often automates this process
- Specialized printers (dye sublimation, inkjet, laser) may not require color separations
Image Types
- Line art images contain only black and white
- Continuous tone images contain shades of gray or color
Halftones
- Technique used to print continuous tone images
- Screens created by a pattern of variable-size dots
- Create an impression of tones with one ink color
Angles for Color Separations
- Color separation screens need to be placed at different angles to prevent moire patterns
- Moire patterns are visual distortions that occur due to overlapping screens
Spot Color (Flat Ink)
- Color produced outside the printing machine by mixing basic inks
- Color composition is specified in color guides (like Pantone)
- Usually used for logos, duotone images, or other graphic elements that require specific colors.
Four-Color Printing (CMYK)
- Uses cyan, magenta, yellow, and black for color reproduction
- Black (K) is often combined with other colors for optimal color intensity without technical problems
Six-Color Printing
- Using additional colors (like modified cyan, magenta, yellow, black, green, or orange) improves the color range
- Stochastic screening is commonly used, eliminating moire patterns
