Understanding theme variables

There are 2 main tables used for base46

• base_30 is used for general UI
• base_16 is used for syntax highlighting
• Use a color lightening/darkening tool, such as this https://imagecolorpicker.com/color-code

Note: the below values are mostly approx values so its not compulsory that you have to use those exact numbers, test your theme i.e show it in the PR to get feedback from @siduck

Default Theme table

-- this line for types, by hovering and autocompletion (lsp required)
-- will help you understanding properties, fields, and what highlightings the color used for
---@type Base46Table
local M = {}
-- UI
M.base_30 = {
  white = "",
  black = "", -- usually your theme bg
  darker_black = "", -- 6% darker than black
  black2 = "", -- 6% lighter than black
  one_bg = "", -- 10% lighter than black
  one_bg2 = "", -- 6% lighter than one_bg
  one_bg3 = "", -- 6% lighter than one_bg2
  grey = "", -- 40% lighter than black (the % here depends so choose the perfect grey!)
  grey_fg = "", -- 10% lighter than grey
  grey_fg2 = "", -- 5% lighter than grey
  light_grey = "",
  red = "",
  baby_pink = "",
  pink = "",
  line = "", -- 15% lighter than black
  green = "",
  vibrant_green = "",
  nord_blue = "",
  blue = "",
  seablue = "",
  yellow = "", -- 8% lighter than yellow
  sun = "",
  purple = "",
  dark_purple = "",
  teal = "",
  orange = "",
  cyan = "",
  statusline_bg = "",
  lightbg = "",
  pmenu_bg = "",
  folder_bg = ""
}

-- check https://github.com/chriskempson/base16/blob/master/styling.md for more info
M.base_16 = {
  base00 = "",
  base01 = "",
  base02 = "",
  base03 = "",
  base04 = "",
  base05 = "",
  base06 = "",
  base07 = "",
  base08 = "",
  base09 = "",
  base0A = "",
  base0B = "",
  base0C = "",
  base0D = "",
  base0E = "",
  base0F = ""
}

-- OPTIONAL
-- overriding or adding highlights for this specific theme only
-- defaults/treesitter is the filename i.e integration there,

M.polish_hl = {
  defaults = {
    Comment = {
      bg = "#ffffff", -- or M.base_30.cyan
      italic = true,
    },
  },

  treesitter = {
    ["@variable"] = { fg = "#000000" },
  },
}

-- set the theme type whether is dark or light
M.type = "dark" -- "or light"

-- this will be later used for users to override your theme table from chadrc
M = require("base46").override_theme(M, "abc")

return M
