Spectrolite

Converter for RGB-based color spaces.

Polished spectrolite lets the colors play.
Please polish this plugin.

Features

• Converts between HEX, RGB, HSL, and Cubehelix color spaces.
• Supports alpha channels for all the color spaces listed above.
• Has options to format lowercase HEX, round HSL and Cubehelix.

For more information about the Cubehelix color space, look for Dave Green's Cubehelix. The specific implementation of Cubehelix for this plugin is described below.

Config

Here is my config using Lazy:

return {
  "shushtain/spectrolite.nvim",
  config = function()
    require("spectrolite").setup({
      lower_hex = false,
      round_hsl = true,
      round_hxl = true,
    })
    vim.keymap.set({ "n", "v" }, "<leader>#h", "<cmd> SpectroliteHex <CR>")
    vim.keymap.set({ "n", "v" }, "<leader>#r", "<cmd> SpectroliteRgb <CR>")
    vim.keymap.set({ "n", "v" }, "<leader>#s", "<cmd> SpectroliteHsl <CR>")
    vim.keymap.set({ "n", "v" }, "<leader>#x", "<cmd> SpectroliteHxl <CR>")
  end
}

Defaults are:

• lower_hex = false
• round_hsl = true
• round_hxl = true

No keymaps are set internally.

I've switched to Neovim quite recently. For the lack of skill, I don't have an example for setting up Packer.

Cubehelix?

Cubehelix colors, in modern terms, are described by hue, saturation, and lightness. Although max saturation for some colors can be close to 500%, the real value of this color space lies in colors with saturation up to 100%. As long as you are within this range, colors of any hue keep constant (accessibility) contrast between their lightness values.

Since the name of this color space is much longer, and the saturation values are quite different from both HSL and (ok)LCH, I've chosen to specify it as hxl.

For example, a button with the background of (240, 100%, 30%) and the text of (240, 100%, 90%) will measure to the same color accessibility contrast as a button with the background of (160, 50%, 30%) and the text of (160, 100%, 90%).

I typically set saturation 110% for signal (error, warning) colors. The clipping (which leads to contrast mutations) is minimal.

I'm not sure I can handle more Lua for now.
Just make a flawless version for me to switch to.
