Oklch Color Picker

Try the web demo: https://oklch.eerolehtinen.fi/

NOTE: This is an application, even though crates.io detects it as a library. The "library" part only exposes lua bindings for color parsing in Neovim.

Features

• Takes an input color as a cli argument and ouputs the edited color to stdout
• Uses a perceptual colorspace (Oklch) to allow intuitive editing
  • Consists of lightness, chroma and hue
  • Motivation: An article by the Oklab creator
  • Oklch uses the same theory as Oklab, but uses parameters that are easier to understand
  • L_r estimate is used instead of L as specified in another article by the same guy
• Supports many color formats for input and output (editing uses only Oklch):
  • Hex (#RGB, #RGBA, #RRGGBB, #RRGGBBAA)
  • Other common CSS formats (rgb(..), hsl(..), oklch(..))
  • Hex literal (0xRRGGBB, 0xAARRGGBB)
  • Any list of 3 or 4 numbers can be used as a color (e.g. 0.5, 0.5, 0.5 or 120, 120, 120, 255)
• Hardware accelerated for maximum smoothness and high resolutions
