Usage

Settings

This package doesn't need any setting.

Models

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

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, image_field, samples

format

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

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.

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.

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).

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.

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 for all color fields. :)
