Is there a way to generate a RGB color by inputting R, G, and B values from 0 up to 255 without using the matplotlib module in python?

Question

Is there a way to generate a color based on its RGB values rather than the following snippet? (And preferably with a more compact module than matplotlib)

from matplotlib.pyplot import scatter, axis, show
R = float(input('Insert R value: '))
G = float(input('Insert G value: '))
B = float(input('Insert B value: '))

def RGB(R,G,B):
  r = R/255
  g = G/255
  b = B/255
  scatter([0],[0],color=(r, g, b), s=1e6)
  axis('off')
  print('R =', R,'nG =', G,'nB =', B)
  show()

RGB(R,G,B)

By inserting the values of R=50, G=100, and B=200 the code above will return the following window, which is basically a matplotlib scatter plot with an expanded dot:

Matplotlib is a huge module and when I try to generate an executable using Pyinstaller the size of the executable gets really big. That’s the reason why I’m asking.

If I’m understanding your requirements properly, how about using pillow module:

from PIL import Image

r = input('Input R value: ')
g = input('Input G value: ')
b = input('Input B value: ')

im = Image.new('RGB', (500, 300), (r, g, b))
im.show()

which will display a rectangle window filled with specified color.
