philiprehberger-color-convert

Convert between color formats: hex, RGB, HSL, HSV, CMYK, and named CSS colors.

Installation

pip install philiprehberger-color-convert

Usage

from philiprehberger_color_convert import Color

# Create from hex
c = Color("#ff6b35")

# Create from CSS named color
c = Color("tomato")

# Create from RGB string
c = Color("rgb(255, 107, 53)")

# Create from another Color
c2 = Color(c)

Factory Methods

c = Color.from_rgb(255, 107, 53)
c = Color.from_hsl(20, 100, 60)
c = Color.from_hsv(20, 79, 100)
c = Color.from_cmyk(0, 58, 79, 0)

Format Properties

c = Color("#ff6b35")

c.rgb   # (255, 107, 53)
c.hex   # "#ff6b35"
c.hsl   # (16, 100, 60)
c.hsv   # (16, 79, 100)
c.cmyk  # (0, 58, 79, 0)

Manipulation

c = Color("#ff6b35")

lighter = c.lighten(20)
darker = c.darken(20)
more = c.saturate(10)
less = c.desaturate(10)
comp = c.complement()
inv = c.invert()

Chaining

# Each method returns a new Color — chain freely
warm = Color("#3498db").desaturate(20).lighten(10)
print(warm.hex)

Palette Generation

c = Color("#ff6b35")

c.analogous()            # [Color, Color, Color]
c.triadic()              # [Color, Color, Color]
c.split_complementary()  # [Color, Color, Color]

Contrast Ratio

white = Color("#ffffff")
black = Color("#000000")

white.contrast_ratio(black)  # 21.0
