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
- Lr 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, 0.5or120, 120, 120, 255)
- Hex (
- Hardware accelerated for maximum smoothness and high resolutions
