Study Notes
Color Gamut
- A color gamut is the range of colors a system can produce.
- It describes the boundaries of the colors that can be displayed or printed.
Imaginary Primary Colors
- The human eye can perceive all colors, including imaginary primary colors.
- These colors don't exist in reality but can be perceived through color mixing.
Color Schemes
- Areas where color schemes are used: design, fashion, art, marketing, and branding.
- NOT an area where color schemes are used: Scientific research (in a generic sense).
Color Balance in Photography
- The main goal of color balance is to achieve accurate color reproduction.
- It aims to ensure that colors in a photograph appear as natural as possible.
Color Adjustment in Images
- The adjustment of the intensities of colors in an image is known as color grading.
- It involves manipulating the hue, saturation, and lightness of colors to enhance visual appeal and storytelling.
Complementary Color Schemes
- A complementary color scheme uses colors that are opposite each other on the color wheel.
- Examples: red and green, blue and orange, yellow and purple.
Significance of Color Schemes in Graphic Design
- Color schemes enhance visual appeal, communicate meaning, and create a cohesive design.
- They help establish a brand identity, evoke emotions, and guide the viewer's attention.
Color Theory Terms
- Hue: A color's pure form, as it appears on the color wheel.
- Saturation: The intensity or purity of a color.
- Value: The lightness or darkness of a color.
- Tint: A color mixed with white to make it lighter.
- Shade: A color mixed with black to make it darker.
Color Balance Adjustment
- Primary colors typically adjusted in color balance: red, green, and blue.
- These primaries are used in digital displays and cameras.
Color Mixing
- The mixture of two complementary colors produces white light.
- This is applicable in both additive color systems (e.g., light) and subtractive color systems (e.g., pigments).
Importance of Color Theory
- Understanding color theory is crucial for media and graphics professionals.
- It enables them to make informed decisions about color choices, create visually appealing designs, and effectively convey messages.
Color Schemes and Descriptions
- Monochromatic: Uses variations of a single hue (e.g., shades of blue).
- Analogous: Uses three hues adjacent on the color wheel (e.g., yellow-green, yellow, and yellow-orange).
- Triadic: Uses three colors evenly spaced on the color wheel (e.g., red, yellow, blue).
- Complementary: Uses two colors opposite each other on the color wheel (e.g., blue and orange).
- Split Complementary: Uses a base color and two colors adjacent to its complement (e.g., blue, yellow-orange, and red-orange).
Isaac Newton's Color Theory
- Isaac Newton proposed the color circle theory, which is a color wheel comprised of pure hues.
- The color circle represents the spectrum of visible light.
Image Data Transformation
- The process of transforming image data from sensors to appropriate values for display is known as color management.
- It involves converting data from different color spaces (e.g., camera sensor, screen, printer) for consistent color reproduction.
Newton's Color Wheel
- The outer circumference of Newton's color wheel contains the chromatic colors, which are pure hues.
- The inner circumference contains the achromatic colors, which are black, white, and gray.
Color Schemes on the Web
- Website color schemes are often used to create brand consistency, enhance user experience, and guide user attention.
- For example, popular websites like Google, Twitter, and Facebook have distinctive color schemes that contribute to their branding.
CMYK Color System
- The 'K' in the CMYK color system represents Key or black.
- It is included to produce deeper blacks and richer shades than a simple mixture of the other three colors (cyan, magenta, yellow).
CMYK Printing Limitations
- The CMYK printing system is less effective at reproducing orange colors.
- This is because orange is a primary color in the additive color system, while in the subtractive system, it is created by mixing other colors.
'Modern Chromatics'
- 'Modern Chromatics', a book on color theory, was written by Ogden N. Rood in 1879.
- It explored scientific and artistic aspects of color, including mixing, perception, and symbolism.
CMY Primary Colors
- CMY primary colors are substances that absorb only one of the retinal primary colors.
- Cyan absorbs only red color, magenta absorbs only green color, and yellow absorbs only blue color.
Artists and Color Theory
- Michelangelo: Used chiaroscuro (contrast between light and dark) and a limited palette to create dramatic effects.
- Leonardo da Vinci: Studied color theory and its effects on perspective and atmosphere.
- Rembrandt: Mastered the use of light and shadow, employing a limited palette to create dramatic scenes.
Expanding Color Range in Printing
- The addition of other colors in the printing process, such as Pantone colors, can expand the range of colors produced.
- Pantone colors are standardized colors used in design and printing, offering a wider selection of colors than CMYK.
Color Harmony
- Color harmony represents a satisfying balance or unity of colors.
- It occurs when colors work well together, creating a harmonious visual impact.
Munsell Color System
- The Munsell Color System was developed by Albert Munsell, a color theorist.
- It is a three-dimensional system that classifies colors based on hue, value (lightness), and chroma (saturation).
Effect of White on Warm Colors
- The color white has a negative effect on warm colors, making them appear less vibrant.
- This is because white reflects light, so when combined with a warm color, it dilutes its vibrancy.
The Color Brown
- Positive aspects of brown: Represents stability, warmth, nature, and comfort.
- Negative aspects of brown: Can be associated with dullness, stagnation, or dirtiness.
Types of Cone Cells
- The three types of cone cells in human vision are red cones, green cones, and blue cones.
- Each cone type is sensitive to a different range of wavelengths, allowing us to perceive a wide spectrum of colors.
Color and Associated Qualities
- Red: Energy, passion, danger, excitement.
- Blue: Peace, tranquility, trust, calmness.
- Green: Nature, growth, harmony, renewal.
- Yellow: Optimism, happiness, energy, cheerfulness.
Colors Found in Brown
- Brown is typically composed of a mixture of colors like red, yellow, orange, and sometimes black.
Perception of Color
- The perception of color is a complex process that involves the eye, the brain, and the environment.
- It starts with the retina but involves higher-level processing in the brain to interpret and decode color information.
Cone Types in Trichromatic Vision
- The three types of cones in trichromatic color vision are sensitive to the following wavelengths:
- Red cones: Long wavelengths (around 560-580 nanometers).
- Green cones: Medium wavelengths (around 530-540 nanometers).
- Blue cones: Short wavelengths (around 420-440 nanometers).
Lens Crystallins
- The main types of crystallins found in the lens are:
- Alpha-crystallin: Largest proportion, contributes to lens transparency.
- Beta-crystallin: Second largest proportion, involved in lens structure and refractive index.
- Gamma-crystallin: Smallest proportion, responsible for lens curvature and flexibility.
Lens Fiber Organization
- Lens fibers are arranged in concentric layers like the layers of an apple, with the older fibers located in the outer layers.
- This layered structure contributes to the lens's transparency and refractive properties.
Accommodation
- The process called accommodation is when the lens changes shape to focus on objects at different distances.
- It is achieved by the ciliary muscles contracting or relaxing, which alters the lens curvature.
Crystallin Properties
- Crystallins are soluble proteins that make up over 90% of the protein within the lens.
- They provide the lens with its transparency and refractive index, allowing for clear vision.
Components of the Lens
- Lens capsule: A thin outer layer that encloses the lens and provides structural support.
- Lens epithelium: A single layer of cells located beneath the capsule, responsible for lens growth.
- Lens fibers: Long, thin cells that make up the bulk of the lens, responsible for transparency and refraction.
Focusing on Nearby Objects
- When focusing on a nearby object, the lens becomes more rounded and thicker.
- This is achieved by the ciliary muscles contracting, pulling the lens capsule and making the lens more convex.
Aquatic Animals
- Aquatic animals rely on their lens for focusing and refractive power like land animals. However, the refractive index of their lens is closer to water than air, which helps them see clearly underwater.
Refractive Index of the Lens
- The refractive index of the lens is not uniform throughout.
- The central layers of the lens have a higher refractive index than the outer layers, which contributes to its focusing power.
