Colour chart for Tkinter and Tix
PythonTkinterTixPython Problem Overview
This isn't a question but an answer to help others that might run into this issue.
I wanted to visualise some basic colours, so I could pick the appropriate ones for my colour scheme. I couldn't find a colour chart anywhere so modified a sample to display it Hope you find it useful.
import Tix as tk

For what it's worth, here's a version that doesn't require Tix. It uses a grid manager so you can see all the colors at the same time. You may want to adjust MAX_ROWS and FONT_SIZE for your display.

Solution 2 - Python
There is also the official colour names documented in the colours man page for Tk.
Solution 3 - Python
What about reading COLORS from a file ?
import sys, os
rgb_path = [
"/usr/share/X11/rgb.txt", #Linux
"/usr/X11/share/X11/rgb.txt", #MacOS
]
COLORS = []
for filename in rgb_path:
if os.path.exists(filename):
with open(filename, 'r') as filedesc:
for line in filedesc:
if not (line.isspace() or line.startswith("#")):
# take the part after the last \t rsplit("\t",[-1])
# and remove the carriage return character [:-1]
COLORS.append(line.rsplit("\t",1)[-1][:-1])
break
Solution 4 - Python
And here's this vehicle reinvented. It uses own implementation of scrolled frame widget
from tkinter import *
class ScrolledFrame(Frame):
def __init__(self, master=None, *args, **kwargs):
top = Frame(master) # create top frame, containing all things
# attach scrollbars
vscroll = Scrollbar(top)
vscroll.pack(side='right', fill='y')
hscroll = Scrollbar(top, orient='horizontal')
hscroll.pack(side='bottom', fill='x')
# hack: insert self into scrollable canvas
canvas = Canvas(top, highlightthickness=0)
canvas.pack(expand=True, fill='both')
super().__init__(master=canvas, *args, **kwargs) # create
canvas.create_window(0,0, window=self,
anchor='nw', tags='frame') # insert
# add a hack to rebuild scrollable area size
canvas.bind('<Configure>', self.__set_scroll)
# cross-bind scrolling
vscroll['command'] = canvas.yview
canvas['yscrollcommand'] = vscroll.set
hscroll['command'] = canvas.xview
canvas['xscrollcommand'] = hscroll.set
# attach hierarchically
self._top = top
self._top._vscroll = vscroll
self._top._hscroll = hscroll
self._top._canvas = canvas
def pack(self, *args, **kwargs):
'''
A wrapper over tkinter's pack
'''
return self._top.pack(*args, **kwargs) # pack topmost
def __set_scroll(self, event=None):
canvas = self._top._canvas
canvas.config(scrollregion=canvas.bbox('frame'))
def showcolors(colors):
colors = colors[:]
root = Tk()
root.title('Tkinter colors showcase')
Label(root, text='Double click to copy to clipboard').pack(fill='x')
top = ScrolledFrame(root)
colnum = int((len(colors)/3) ** 0.5)
row = 0
while colors:
chunk, colors = colors[:colnum], colors[colnum:]
for col, color in enumerate(chunk):
lab = Label(top, text=color, bg=color)
lab.grid(row=row, column=col, sticky='wens')
lab.bind('<Double-1>', _clipboard_copy(lab))
lab.bind('<Enter>', lambda ev, lab=lab: lab.config(fg='white'))
lab.bind('<Leave>', lambda ev, lab=lab: lab.config(fg='black'))
row += 1
top.pack(expand=True, fill='both')
root.mainloop()
def _clipboard_copy(inst):
def wrapper(event):
inst.clipboard_clear()
inst.clipboard_append(inst['text'])
return wrapper

It's something like Tcl/Tk's showcase, but pythonic)
Solution 5 - Python
Incorporating some of the other answers into a definitive version complete with:
- scrolling;
- copying color hexcode to clipboard;
- using a built-in color list;
- white text on dark colors;
- adjusting for modern high-DPI displays;
The official tkinter colors man page is derived from the X11 color names, and a version should be included in your python installation under %PYTHONPATH%/Tools/pynche/X/rgb.txt . Here is a detailed explanation on the formulas used to calculate a proper text color based on contrast and luminance.
import tkinter as tk
from Tools.pynche import ColorDB
import os
import colorsys
rgb_file = os.path.join(os.path.dirname(ColorDB.__file__), 'X', 'rgb.txt')
rgb_db = ColorDB.get_colordb(rgb_file)
colors = [x.lower().replace(' ', '') for x in rgb_db.unique_names()]
# Separating the grayscale looks nicer
grayscale = []
for v in ['black'] + ['gray{}'.format(i) for i in range(0, 101)] + ['white']:
if v in colors:
colors.remove(v)
grayscale.append(v)
colors.sort(key=lambda x: colorsys.rgb_to_hls(*rgb_db.find_byname(x)))
colors = grayscale + colors
# Use white on dark colors, black on light
def calculateContrast(color):
# Converting to 8 bit from 16 bit, and diving by 255 (255 * 256 = 65280)
rgb = [c / 65280 for c in color]
r, g, b = [(c / 12.92) if c <= 0.03928 else
((c + 0.055) / 1.055) ** 2.4 for c in rgb]
luminance = 0.2126 * r + 0.7152 * g + 0.0722 * b
if luminance > 0.179:
return '#000000'
else:
return '#ffffff'
