colorx - extra color models

Lint & Test

This package contains extra color models to complement the models in image/color. By using a different color model than the default color.RGBA model, you can specify or modify the color in a different way.

Import: github.com/somebadcode/go-colorx/v2

HSV/HSB - Hue, Saturation, Value/Brightness

HSV is implemented through the concrete type HSVA. The HSV color model was designed to more closely reflect how humans perceive colors. You can use HSV to generate gradients or a color palette for graphs that are easier to perceive for colorblind users. You can also use this color model to make images monochrome or have more saturated colors.

HSL - Hue, Saturation, Lightness

HSL is similar to HSV and can be more useful in some use cases.

CSS - Cascading Style Sheets

A variation of the RGBA color model where the alpha/opacity is stored as a floating point number between 0.0 and 1.0. This allows you to work with the colors using the image/colors package and convert it to this special color model that can give you strings that specify the color according to CSS specifications. The CSS color model implements the stringer interface.

Examples:

  • rgb(255,191,128)
  • rgba(255,191,128,0.75)
  • #FFBF80
  • #FFBF80BF
