Claritas

Library for generating different variations of brightness for given color.

Installation

The package can be installed by adding claritas to your list of dependencies in mix.exs:

def deps do
  [
    {:claritas, "~> 0.1.1"}
  ]
end

and running mix deps.get in your console to fetch from Hex.

Basic Usage

positive values are lightening the color

iex> Claritas.shift("#f06d06", 30)
{:ok, "#FF8B24"}

negative values are darkening the color

iex> Claritas.shift("#f06d06", -30)
{:ok, "#D24F00"}

Dynamically increase/decrease brightness of your colors.

Controller:

def index(conn, _params) do
  shades =
    for i <- 1..20, into: [] do
      Claritas.shift("#141C5B", 10 * i)
    end

  render(conn, "index.html", shades: shades)
end

<ul>
  <%= for {_, shade} <- @shades do %>
