blue= (0, 0, 128)

red= (128, 0,0)
yellow= (255, 255,0)
cyan= (0, 255, 255)
magenta= (255,0, 255)
purple= ( 160, 32, 240) ------------------ that's 11 colors
What's a good way to choose 15 colors? Or 20 colors? Or more?
1) choose from lists of predefined colors

2) predefine and name your own colors manually, then pick the colors at
random from a list
3) generate random r,g,b values between 0 and 255, and name the
resultant colors.
4) generate r,g,b values in ranges known to produce greens, reds, blues,
oranges, yellows, etc. You could name them consecutively: green1,
green2, green3...
Post by HenHanna (adjacent colors should look different)
What are 'adjacent colors'?
black= (0,0,0)
white= (255,255,255) .............
from PIL import Image
from PIL import ImageDraw
def newImg():
img = Image.new('RGB', (120, 120))
for i in range(100):
img.putpixel((10+i,10+i), (red, black, white)[i%3])
img.save('test.gif')
return img
Thanks.... for what i mean by [adjacent] pls see above.
............good ways to choose 15, 20, or more colors in Python,
ensuring adjacent colors look different:
1. Colormaps:
Import libraries:
Python
import matplotlib.pyplot as plt
from matplotlib.cm import get_cmap
Choose a colormap:
There are many built-in colormaps in Matplotlib. Some that provide good
visual distinction between adjacent colors include:
viridis
plasma
inferno
cividis
coolwarm (for diverging color schemes)
