- Circular diagram that arranges colors according to their hue
- Helps visualize color relationships and create harmonious color schemes
- Primary colors are the three base colors that cannot be created by mixing other colors
- Red, blue, and yellow in the traditional color wheel
- All other colors are derived from combinations of primary colors
- Secondary colors are created by mixing two primary colors
- Orange (red + yellow), green (blue + yellow), and purple (red + blue)
- Provide additional variety and depth to color palettes
- Tertiary colors are created by mixing a primary color with an adjacent secondary color
- Red-orange, yellow-orange, yellow-green, blue-green, blue-purple, and red-purple
- Offer even more nuance and subtlety in color schemes
Color Temperature
- Color temperature describes the perceived warmth or coolness of a color
- Warm colors (reds, oranges, yellows) evoke feelings of warmth, energy, and excitement
- Cool colors (blues, greens, purples) evoke feelings of calmness, relaxation, and tranquility
- Understanding color temperature helps create emotional impact and visual interest in designs
- Warm colors can be used to draw attention, create a sense of urgency, or convey passion
- Cool colors can be used to create a sense of stability, professionalism, or serenity
Color Harmony and Psychology
Color Harmony

- Colors that work well together create a sense of balance and visual appeal
- Harmonious color schemes can be created using color wheel relationships (complementary, analogous, triadic)
- are opposite each other on the color wheel (red and green, blue and orange)
- Create high contrast and visual interest when used together
- Should be used sparingly to avoid overwhelming the viewer
- are adjacent to each other on the color wheel (blue, blue-green, green)
- Create a sense of harmony and cohesion in designs
- Often found in nature and can evoke feelings of calmness and serenity
Color Psychology and Associations
- studies the emotional and behavioral effects of colors on people
- Colors can evoke specific emotions, moods, and associations
- Understanding color psychology helps create effective and impactful designs
- Common color associations include:
- Red: passion, energy, excitement, danger
- Blue: trust, stability, calmness, professionalism
- Green: growth, nature, freshness, harmony
- Yellow: happiness, optimism, creativity, caution
- Cultural color meanings vary across different societies and contexts
- White: purity and innocence in Western cultures; mourning and death in some Eastern cultures
- Red: good luck and celebration in Chinese culture; danger and warning in Western cultures
