palgrad is a command line utility that creates color gradients and palettes from user input colors.
Gradients are created in Lch color space (also known as HCL), the cylindrical representaiton of the Lab or L*a*b* color space. Using this color space, gradients are generally more vibrant and visually appealing than other spaces like HSV or RGB.
- Radial and linear continuous gradients
- Radial continuous gradients with overlay
- Radial and linear stepped gradients
- Declare colors in
Lch,HSV, andRGB
Some ideas for using the output:
- gamut masking
- pixelization to make more color swatches
- bring into digital painting programs to color pick from as limited palettes and apply more filters
- website/application color themes
This crate uses palette to handle the heavy lifting of color conversion.
palgrad -c -o -s 128Overlay a 50% grey over the default RGB colors in -c with a size of 128x128 pixels. An overlay RGB color can be specified after the -o argument.
palgrad --hsv -n 5 -s 128 -r 0.25Use the default HSV colors --hsv, 5 steps between the colors, size of 128x128, and inner radius factor of -r 0.25.
palgrad -l -d -n 8 --ss 30x20Make a linear gradient -l with the default RGB decimal colors -d, 8 steps between the two colors, and the swatch sizes are 30x20 pixels each. To make a continuous gradient, omit the steps argument -n.
