What theme is this?

It doesnt look like the normal rose-pine one? I like how it's more muted

[cruzluna]

use({
      'rose-pine/neovim',
      as = 'rose-pine',
      config = function()
          vim.cmd('colorscheme rose-pine')
      end
  })

in addition to @cruzluna answer, in after/plugin/colors.lua he modifies the background transparency:

require('rose-pine').setup({
    disable_background = true
})

function ColorMyPencils(color) 
    color = color or "rose-pine"
    vim.cmd.colorscheme(color)

    vim.api.nvim_set_hl(0, "Normal", { bg = "none" })
    vim.api.nvim_set_hl(0, "NormalFloat", { bg = "none" })

end

ColorMyPencils()
