# Chameleon
Chameleon is a utility that converts colors from one model to another.
It currently supports: Hex, RGB, CMYK, HSL, Pantone, and Keywords.
## Use
Conversion requires a color value, an input color model, and an output
color model.
Example: `Chameleon.convert("FFFFFF", :hex, :rgb) -> {:ok, %{r: 255, g: 255, b: 255}}`
If a translation cannot be made, the response will be an error tuple with
the input value returned.
Example: `Chameleon.convert("F69292", :hex, :pantone) -> {:error, "F69292"}`
In this example, there is no pantone value that matches that hex value, but
an error could also be caused by a bad input value;
Example: `Chameleon.convert("Reddish-Blue", :keyword, :hex)`
## Caveat(s)
Pantone is designed to be used on printed work only. As such, it is disingenuous to say a
pantone value can be translated to a hex value since hex values will look different depending
on the device displaying them. However, if you have a pantone value and want to find a
device-displayable analog, this library will work.
## Installation
The package can be installed by adding `chameleon` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:chameleon, "~> 1.0.0"}
]
end
```
## Contribution
Contributions are welcomed. Please open a pull request or file an issue with your ideas.
Some ideas would be:
* add a new color model for conversion
* add functionality to generate complementary colors
* handle errors for invalid input values
