vcolorpicker

Simple visual Color Picker with a modern UI created with Qt to easily get color input from the user.

Installation

1. Install using pip:

   pip install vcolorpicker
   

   or clone the repository yourself and run:

   pip install .
   

Usage

2. To ask for a color, import the getColor function and run it:

   from vcolorpicker import getColor
   
   color = getColor()

Customization

• Showing custom last color:

  old_color = (255,255,255)
  picked_color = getColor(old_color)

• Changing the UI Theme

  from vcolorpicker import useLightTheme
  
  useLightTheme(True)

• Adding Alpha selection

  from vcolorpicker import useAlpha
  
  useAlpha(True)

  When the ColorPicker uses Alpha, you have to pass a RGBA tuple
  as the last color, otherwise there wil be an error.

  old_color = (255,255,255,100)
  picked_color = getColor(old_color)  # => (r,g,b,a)

Color Formats and Conversion

• The default format getColor will give you is RGB(A),
  but you can use vcolorpickers color conversion functions
  if you have a different format like HSV or HEX.

  hsv2rgb HSV(A) to RGB(A)
  rgb2hsv RGB(A) to HSV(A)
  rgb2hex RGB(A) to HEX
  hex2rgb HEX to RGB
  hex2hsv HEX to HSV
  hsv2hex HSV(A) to HEX

• Example:

  from vcolorpicker import getColor, hsv2rgb, rgb2hsv 
  
  old_color = hsv2rgb((50,50,100,100))  # => (127,255,255,100)
  
  picked_color = rgb2hsv(getColor(old_color))

• Color Formats:

  RGB values range from 0 to 255
  HSV values range from 0 to 100
  HEX values should be in format: "XXXXXX" or "xxxxxx"
  Alpha values range from 0 to 100

Compatibility

This package is compatible with Python 3.7+ and above. It uses qtpy under the hood, so it should work with all Qt bindings (PyQt5, PySide2, PySide6, PyQt6).

Previous versions

In previous versions you had to create a ColorPicker object first and then
call it's getColor method. This is still supported, you just have to
import the ColorPicker class.

The color conversion functions are not methods anymore, you can import them
directly with from vcolorpicker import hsv2rgb, rgb2hsv.

You also had to create a QApplication object before being able to run the
ColorPicker, now it automatically creates one by itself if there isn't one yet.
If you need to get the auto-created application, you can use this:

from PyQt5.QtWidgets import QApplication
app = QApplication.instance()
