The first problem is that you are posting in HTML which is losing
all the code formatting, making it hard to read.

Also you don't actually tell us what doesn't work. If you get an
error message post it. If you get different results to what you
expect tell us what you expect and what you got.

For now I'll take a guess below...

number = int(input('Enter a number between 0 and 36: '))
green_number = (0)
red_number = (1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 
34, 36)
black_number = (2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 34, 
29, 31, 33, 35)
if number == green_number:
     print('Number is Green')
elif number == red_number:
     print('Number is Red')
elif number == black_number:
         print('Number is Black')

Note that you are testing the number for equality, which means it
must be exactly the same value.

But your red_number and black_number are both tuples of several
numbers so a single number will never equal a sequence of numbers.
You should use the 'in' test instead of equals.

Like

if number in red_number:
