Study Notes
Image Representation
- An image is divided into small areas called pixels (picture elements) to translate it into numbers.
- Each pixel has a particular color, with modern computers able to show up to 16.7 million different colors.
Color Representation
- Colors are represented as a combination of three primary colors: red, green, and blue (RGB color model).
- Color depth refers to the total number of colors a screen can render, measured in bits.
- Different color depths include:
- 3bit: 8 colors
- 8bit: 256 colors
- 24bit: 16.78 million colors
Color Theory
- The color wheel consists of primary colors, secondary colors, and a full color wheel.
- Color schemes include:
- Monochromatic
- Analogous
- Complementary
- Split-complementary
- Triadic
- Tetradic
Color Terminologies
- Hue: the color of an object
- Saturation: the strength or weakness of a color
- Chroma: the purity of a color
- Shade: created by adding black to a pure hue
- Tone: created by adding grey to refine a color
- Value: shows how light or dark a hue is
Color Meanings
- Yellow: joy, positive energy, zest
- Black: mystery, power, grace, mature

- White: purity, cleanliness, perfection, sophisticated
- Purple: royalty, luxurious, creative
- Pink: feminine, safe, delightful
- Orange: creativity, intelligence, initiative, enthusiasm
- Grey: elegance, uncertainty
Raster vs Vector Graphics
- Raster graphics:
- Made up of pixels
- Resolution dependent
- Cannot be scaled without losing quality
- Best for photo-realistic elements
- File formats: BMP, GIF, JPEG, PNG
- Vector graphics:
- Composed of geometric primitives and mathematical equations
- Resolution independent
- Can be scaled to any size without losing quality
- Best for cartoon-like images and 3D modeling
- File formats: Flash, Scalable Vector Graphics (SVG), CDR (CorelDraw), AI (Adobe Illustrator)
Vector Graphics
- Based on mathematical formulas
- Can be easily edited and modified
- Smaller file sizes than raster graphics
- Used for logos, illustrations, and precise shapes and lines
Color Palettes
- Monochromatic: same hue in different shades and tones
- Analogous: consistent images and texts with different shades of the same hue
- Complementary: opposite colors in the color wheel (e.g. red and green)
- Triadic: three colors at equidistant points in the color wheel (e.g. red, yellow, and blue)
