Bug: The text completely blends with the background color of nvim and becomes unreadable. Happens in 'foreground' mode.

[decipher-cs]

Describe the bug
I'm using the tokyonight-night theme and any hex color with dark value just blends with the background when I set mode = foreground

To Reproduce
Use this config and open any file with a hex color whose value is close to your theme's background color. The text will blend.
I'm using the lazy plugin for setup and installation.

{
  "norcalli/nvim-colorizer.lua",
  config = function()
      require("colorizer").setup({}, { mode = "foreground" })
  end
},

Expected behavior
I expected it to use some type of contrast detection algorithm and automatically switch the blending text to background mode.
