---

## Installation
-   Run `pip install django-colorfield`
-   Add `colorfield` to `settings.INSTALLED_APPS`
-   Run `python manage.py collectstatic`
-   Restart your application server

---

## Usage

### Settings
This package doesn't need any setting.

### Models
Just add color field(s) to your models like this:

```python
from colorfield.fields import ColorField
from django.db import models

class MyModel(models.Model):
    color = ColorField(default='#FF0000')
```

### Field Options
These are the supported custom options: [`format`](#format), [`image_field`](#image_field), [`samples`](#samples)

#### format

The following formats are supported: `hex` *(default)*, `hexa`, `rgb`, `rgba`.

```python
from colorfield.fields import ColorField
from django.db import models

class MyModel(models.Model):
    color = ColorField(format="hexa")
```

#### image_field

It is possible to auto-populate the field value getting the color from an image using the `image_field` option.

The color will be calculated from the **top-left pixel** color of the image each time the model instance is saved.

```python
from colorfield.fields import ColorField
from django.db import models

class MyModel(models.Model):
    image = models.ImageField(upload_to="images")
    color = ColorField(image_field="image")
```

#### samples

It is possible to provide a palette of colors to choose from to the widget using the `samples` option.

This option **is not restrictive** (on the contrary of `choices` option), it is also possible to choose another color from the spectrum.

![django-colorfield-samples](https://user-images.githubusercontent.com/7900305/104512178-194d3600-55ee-11eb-8cba-91cca156da06.png)

```python
from colorfield.fields import ColorField
from django.db import models

class MyModel(models.Model):

COLOR_PALETTE = [
        ("#FFFFFF", "white", ),
        ("#000000", "black", ),
    ]

# not restrictive, allows the selection of another color from the spectrum.
    color = ColorField(samples=COLOR_PALETTE)

# restrictive, it is mandatory to choose a color from the palette
    color = ColorField(choices=COLOR_PALETTE)
```

### Forms

#### Model forms

The `colorfield.fields.ColorField` can be used in Django model forms (`django.forms.ModelForm`) to provide a color picker widget.
When used in a model form, the field automatically validates the color format based on the specified `format` (e.g., `hex`, `rgb`, `rgba`).

```python
from django import forms

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ["color"]
```

#### Plain forms

The `colorfield.forms.ColorField` can be used in plain Django forms (`django.forms.Form`) to provide a color-picker widget.
This is useful when you need a color input outside of a model context.

```python
from django import forms
from colorfield.forms import ColorField

class MyForm(forms.Form):
    color = ColorField(initial="#FF0000", format="hex")
```

### Admin
The admin will kindly provide a simple [color picker](https://coloris.js.org/) for all color fields. :)
