               worldwide, non-exclusive, no-charge, royalty-free, irrevocable
               copyright license to reproduce, prepare Derivative Works of,

            3. Grant of Patent License. Subject to the terms and conditions of
               this License, each Contributor hereby grants to You a perpetual,

               (except as stated in this section) patent license to make, have made,
               use, offer to sell, sell, import, and otherwise transfer the Work,
               where such license applies only to those patent claims licensable
               by such Contributor that are necessarily infringed by their
               Contribution(s) alone or by combination of their Contribution(s)
               with the Work to which such Contribution(s) was submitted. If You

               granted to You under this License for that Work shall terminate
               as of the date such litigation is filed.
         
            4. Redistribution. You may reproduce and distribute copies of the
               Work or Derivative Works thereof in any medium, with or without
               modifications, and in Source or Object form, provided that You
               meet the following conditions:
         
               (a) You must give any other recipients of the Work or
                   Derivative Works a copy of this License; and
         
               (b) You must cause any modified files to carry prominent notices
                   stating that You changed the files; and
         
               (c) You must retain, in the Source form of any Derivative Works
                   that You distribute, all copyright, patent, trademark, and
                   attribution notices from the Source form of the Work,
                   excluding those notices that do not pertain to any part of
                   the Derivative Works; and
         
               (d) If the Work includes a "NOTICE" text file as part of its
                   distribution, then any Derivative Works that You distribute must
                   include a readable copy of the attribution notices contained
                   within such NOTICE file, excluding those notices that do not
                   pertain to any part of the Derivative Works, in at least one
                   of the following places: within a NOTICE text file distributed
                   as part of the Derivative Works; within the Source form or
                   documentation, if provided along with the Derivative Works; or,
                   within a display generated by the Derivative Works, if and
                   wherever such third-party notices normally appear. The contents
                   of the NOTICE file are for informational purposes only and
                   do not modify the License. You may add Your own attribution
                   notices within Derivative Works that You distribute, alongside
                   or as an addendum to the NOTICE text from the Work, provided
                   that such additional attribution notices cannot be construed
                   as modifying the License.
         
               You may add Your own copyright statement to Your modifications and
               may provide additional or different license terms and conditions
               for use, reproduction, or distribution of Your modifications, or
               for any such Derivative Works as a whole, provided Your use,
               reproduction, and distribution of the Work otherwise complies with
               the conditions stated in this License.
         
            5. Submission of Contributions. Unless You explicitly state otherwise,
               any Contribution intentionally submitted for inclusion in the Work
               by You to the Licensor shall be under the terms and conditions of
               this License, without any additional terms or conditions.
               Notwithstanding the above, nothing herein shall supersede or modify
               the terms of any separate license agreement you may have executed
               with Licensor regarding such Contributions.
         
            6. Trademarks. This License does not grant permission to use the trade
               names, trademarks, service marks, or product names of the Licensor,
               except as required for reasonable and customary use in describing the
               origin of the Work and reproducing the content of the NOTICE file.
         
            7. Disclaimer of Warranty. Unless required by applicable law or
               agreed to in writing, Licensor provides the Work (and each
               Contributor provides its Contributions) on an "AS IS" BASIS,
               WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
               implied, including, without limitation, any warranties or conditions
               of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
               PARTICULAR PURPOSE. You are solely responsible for determining the
               appropriateness of using or redistributing the Work and assume any
               risks associated with Your exercise of permissions under this License.
         
            8. Limitation of Liability. In no event and under no legal theory,
               whether in tort (including negligence), contract, or otherwise,
               unless required by applicable law (such as deliberate and grossly
               negligent acts) or agreed to in writing, shall any Contributor be
               liable to You for damages, including any direct, indirect, special,
               incidental, or consequential damages of any character arising as a
               result of this License or out of the use or inability to use the
               Work (including but not limited to damages for loss of goodwill,
               work stoppage, computer failure or malfunction, or any and all
               other commercial damages or losses), even if such Contributor
               has been advised of the possibility of such damages.
         
            9. Accepting Warranty or Additional Liability. While redistributing
               the Work or Derivative Works thereof, You may choose to offer,
               and charge a fee for, acceptance of support, warranty, indemnity,
               or other liability obligations and/or rights consistent with this
               License. However, in accepting such obligations, You may act only
               on Your own behalf and on Your sole responsibility, not on behalf
               of any other Contributor, and only if You agree to indemnify,
               defend, and hold each Contributor harmless for any liability
               incurred by, or claims asserted against, such Contributor by reason
               of your accepting any such warranty or additional liability.

---

## Installation

Install the package directly from pip:

```bash
pip install material-color-utilities
```

---

## Features

- **Theming**
    - Generate Material Design themes from source colors or images.
- **Image Processing**
    - Extract prominent colors from images.
- **Contrast Ratio**
    - Calculate contrast ratios between colors.

---

## Usage

Complete API documentation here: [API docs](https://github.com/RuurdBijlsma/material-color-utilities/blob/main/docs/api.md).

### Importing the Library

```python
from material_color_utilities import (
    CustomColor,
    Variant,
    argb_from_hex,
    hex_from_argb,
    prominent_colors_from_image,
    theme_from_color,
    theme_from_image,
    get_contrast_ratio
)
```

### Generate a Theme

#### From a Source Color

```python
theme = theme_from_color("#FC03A3", 0, Variant.EXPRESSIVE)
# now apply the theme somewhere
# Example, assuming dark theme:
button.color = theme.schemes.dark.primary
button.text_color = theme.schemes.dark.on_primary
background.color = theme.schemes.dark.surface_container
text_paragraph.color = theme.schemes.dark.on_surface
```

#### From an Image

This package will handle converting to RGBA and resizing for performance, so any PIL image can be passed.

```python
from PIL import Image

image = Image.open("path/to/image.jpg")
# You can *optionally* pass a list of custom colors to generate palettes that harmonize with the source color.
custom_colors = [CustomColor("#4285F4", "Google Blue", True)]
theme = theme_from_image(image, 0, Variant.CONTENT, custom_colors)
```

#### Theme to dict

A `Theme` object can be converted to a dict, an example theme dict can be found [here](https://github.com/RuurdBijlsma/material-color-utilities/blob/main/docs/theme_dict_example.py).

```python
theme = theme_from_color("#FF0000")
theme_dict = theme.dict()
```

### Extract Prominent Colors from an Image

This package will handle converting to RGBA and resizing for performance, so any PIL image can be passed.

```python
from PIL import Image

image = Image.open("path/to/image.jpg")
colors = prominent_colors_from_image(image, 5)
print(colors)  # Outputs a list of up to 5 prominent colors
```

### Calculate Contrast Ratio

```python
ratio = get_contrast_ratio("#000000", "#FFFFFF")
print(ratio)  # Outputs: 21.0
```

### Convert Colors

#### ARGB from HEX

```python
argb = argb_from_hex("#4285f4")
print(argb)  # Outputs: 4286017588 (0xFF4285F4)
```

#### HEX from ARGB

```python
hex_color = hex_from_argb(0xFF4285F4)
print(hex_color)  # Outputs: "#4285f4"
```
