Definition of Tkinter Color Chart
Tkinter color chart is one of the modules of Tkinter library which gives programmers the ability to choose a color of their choice easily from the already available set of bulk colors for developing an enhanced GUI. Tkinter color chart with a range of all the varieties of color is being devised by Tkinter and Hortsmann graphics library available in python which is extensively used for identifying different colors. A semantic program can be used to generate and create the Tkinter color chart which is quite advantageous when compared with direct usage of Tkinter color for creating an enhanced GUI.
Syntax:
Since Tkinter color chart is an extension to the Tkinter colors it is represented as follows :
Import tkinter as tk
Colors = [
list of colors as per color chart
]
Call for the necessary methods;
mainloop();
The syntax flow has significance in a way that the Tkinter module represented as tk is used for importing the necessary packages and then the variable colors is declared which contains all the necessary colors as per chart which is then called by any of the methods as per requirement. Finally, the mainloop method is called in order to put all the overlapping changes.
How to Create Color Chart in Tkinter?
There is not much of difference in Tkinter module when incorporated with colors but still, a very little difference exists with the fact that it can be called an extension to colors attribute means that the Tkinter color chart is an extension to the color attribute of the Tkinter standard library providing an ability to the programmers or developers to choose any random color of choice at one go. Let’s check the creation of a color chart using Tkinter in a bit detail.
- Import the Tkinter module or say the standard library tk to support the functionality.
- Declare and define the variable representing colors in the chart format I.e. declare the Tkinter color chart containing colors like ‘gray’, ‘green’, ‘cyan’, ‘violet’ etc. It will contain colors including colors in RGB[Red, Green, Blue] color with a normal format.
- Call for any of the methods like for sorting the colors, or to arrange the color in a format like grid method, pack method, etc.
- And End by calling the mainloop which will apply the necessary changes on top of it for the changes and stuffs to be continued for working.
Constructor
There is no specific constructor to be passed for any specific method only for Tkinter color chart. It all depends on the method that needs to be used with a specific reason and that’s what signifies when values are passed on to the variable to be used for the creation of application and that application completely depends on the random selection of color present on the color chart. So, some list of mandatory colors as part of the Tkinter tk module which are mandatory and is mentioned in many of the Tkinter based color charts. Taking example and elicitation might simplify the use of constructors.
Example: Any application wants to display the message to be highlighted with some specific color then it will include parameters such as config(bg=’yellow’) which means the color to be set as background color should be yellow. Similarly, some list of parameters that is used by the widget for setting the colors once selected from the color chart :

- bg: to set any background color normally in the entire canvas.
- activebackground: to set the background color once the widget is decided to be placed under the cursor.
- activeforeground: to set the foreground color once the widget is decided to be placed under the cursor.
- Highlightcolor: This is the parameter related to color which is often used with texts to highlight any specific text with color.
Methods
There are certain methods that need to be used frequently when color charts are used for implementation. These color charts are mostly used and emphasized for the creation of gaming applications.
The following methods are used for the creation of Tkinter color chart based applications:
- Pack() method
- Grid() method
- Place() method
# Pack() Method: Pack() Method is the method that is used for organizing the widgets in the format of blocks before placing the main or the parent widget.
# Grid() Method: Grid() Method is the method as part of the standard Tkinter standard library which is used for organizing the widgets in the grid format means table-like structure before placing it in the parent or the main window for accommodating the widgets in a format.
# Place() Method: Place() Method is the method which is another important module of the standard library of Tkinter which is used for organizing the widget in a format where the programmer accommodates the widget by placing and keeping them on the instructed path and specified position as per programmer requirement.
Example of Tkinter Color Chart
This program demonstrates the clear usage of the Tkinter color chart which can be used appropriately as per program requirement as shown in the output.
Code:
import tkinter as tk
COL_ORS = [
'IndianRed1','firebrick1', 'coral1', 'HotPink2', 'brown1',
'red2', 'gray1', 'VioletRed1', 'purple2', 'goldenrod1', 'SeaGreen1' , 'OliveDrab2', 'DarkGoldenrod1', 'DarkOrchid3',
'floral white', 'magenta4', 'pink4', 'LightYellow3', 'LightCyan3', 'turquoise2', 'OliveDrab4', 'thistle4'
]
class Color_Chart(tk.Frame):
Mx_Rw = 32
Fnt_Sz = 12
def __init__(slf, r_t):
tk.Frame.__init__(slf, r_t)
rw = 0
cl = 0
for color in COL_ORS:
label = tk.Label(slf, text=color, bg=color,
font=("Times", slf.Fnt_Sz, "bold"))
label.grid(row=rw, column=cl, sticky="ew")
rw += 1
if rw > slf.Mx_Rw:
rw = 0
cl += 1
slf.pack(expand=1, fill="both")
if __name__ == '__main__':
r_t = tk.Tk()
r_t.title("Tkinter_Color_Chart")
app = Color_Chart(r_t)
r_t.mainloop()
Output:
Conclusion
It is a very enhanced and versatile feature for the programmers because of the flexibility and range of options it provides to the programmers in terms of implementation of color-based GUI for applications at one go as shown in the previous program. It helps to enhance and create eye-catching applications GUI filled with complicated colors with respect to the Tkinter color chart.
