Understanding Color Formats

🎨 Color Format Explanations

HEX (Hexadecimal)

Format: #RRGGBB or #RGB

Range: 00-FF for each channel

Example: #3498DB, #F39C12

Use Case: Web development, CSS styling

HEX colors use hexadecimal notation where:

RR: Red component (00-FF)
GG: Green component (00-FF)
BB: Blue component (00-FF)

Short form: #RGB expands to #RRGGBB (e.g., #F39 → #FF3399)

RGB (Red, Green, Blue)

Format: rgb(r, g, b) or rgba(r, g, b, a)

Range: 0-255 for each channel

Example: rgb(52, 152, 219), rgba(52, 152, 219, 0.8)

Use Case: Digital displays, programming

RGB is an additive color model where:

Red: Red light intensity (0-255)
Green: Green light intensity (0-255)
Blue: Blue light intensity (0-255)
Alpha: Transparency (0.0-1.0, optional)

Common values: Black (0,0,0), White (255,255,255), Red (255,0,0)

HSL (Hue, Saturation, Lightness)

Format: hsl(h, s%, l%) or hsla(h, s%, l%, a)

Range: H: 0-360°, S: 0-100%, L: 0-100%

Example: hsl(204, 70%, 53%), hsla(204, 70%, 53%, 0.8)

Use Case: Design, color theory, intuitive color selection

HSL represents colors in a more intuitive way:

Hue: Color wheel position (0-360°)
Saturation: Color intensity (0-100%)
Lightness: Brightness level (0-100%)
Alpha: Transparency (0.0-1.0, optional)

Hue examples: Red (0°), Yellow (60°), Green (120°), Blue (240°)

CMYK (Cyan, Magenta, Yellow, Key/Black)

Format: cmyk(c%, m%, y%, k%)

Range: 0-100% for each channel

Example: cmyk(76%, 31%, 0%, 14%)

Use Case: Print design, professional printing

CMYK is a subtractive color model for printing:

Cyan: Cyan ink percentage (0-100%)
Magenta: Magenta ink percentage (0-100%)
Yellow: Yellow ink percentage (0-100%)
Key (Black): Black ink percentage (0-100%)

Note: Colors may appear different when printed vs displayed on screen

HSV/HSB (Hue, Saturation, Value/Brightness)

Format: hsv(h, s%, v%)

Range: H: 0-360°, S: 0-100%, V: 0-100%

Example: hsv(204, 76%, 86%)

Use Case: Color pickers, image editing software

HSV is similar to HSL but uses Value instead of Lightness:

Hue: Color wheel position (0-360°)
Saturation: Color purity (0-100%)
Value: Brightness/intensity (0-100%)

Difference from HSL: Value represents the brightness of the color itself

Color Theory and Harmony

🎭 Understanding Color Relationships

Monochromatic

Definition: Different shades, tints, and tones of a single hue

Characteristics: Harmonious, calming, unified appearance

Use Case: Minimalist designs, creating depth without contrast

Example: Light blue, medium blue, dark blue, navy blue

Analogous

Definition: Colors adjacent to each other on the color wheel

Characteristics: Pleasing to the eye, natural harmony

Use Case: Nature-inspired designs, gradients

Example: Blue, blue-green, green (30° apart on color wheel)

Complementary

Definition: Colors opposite each other on the color wheel

Characteristics: High contrast, vibrant, attention-grabbing

Use Case: Call-to-action buttons, emphasis, bold designs

Example: Blue and orange, red and green (180° apart)

Triadic

Definition: Three colors evenly spaced on the color wheel

Characteristics: Vibrant, balanced, dynamic

Use Case: Playful designs, children's content, energetic brands

Example: Red, yellow, blue (120° apart)

Tetradic (Rectangle)

Definition: Four colors forming a rectangle on the color wheel

Characteristics: Rich, diverse, complex harmony

Use Case: Complex designs, varied content, professional layouts

Example: Red, yellow-green, cyan, blue-violet

Split Complementary

Definition: Base color plus two colors adjacent to its complement

Characteristics: High contrast with less tension than complementary

Use Case: Balanced designs with visual interest

Example: Blue with red-orange and yellow-orange
