punchagan / prang

A python script that shows the color name at the pixel where the mouse is present

Description

A simple python script that gives the color of the pixel at which the mouse is pointed. This script is intended to serve as an aid to people who are color-blind.

Installation

Windows

1. Install Python
2. Install pywin32
3. Get the source code of prang and execute the script prang.py.

Unix/Linux

1. Install Python
2. Install pygtk
3. Install python-xlib
4. Install PyZenity
5. Get the source code of prang and execute the script prang.py.

How it works

1. It picks up the RGB values of the pixel at which the mouse pointer is present.
2. Looks up the color from a look-up table and returns the color if, it is present in the look-up table.
3. Else, calculates the nearest neighbor and returns the name of that color. [An asterisk indicates this approximation]
4. This color name is then shown in a pop-up window.

Ideally, this script should be hooked to a short-cut key, so as to run it with ease.
