1300 total chips and I could run a few different tournaments with that set-up.
25 players for a T10,000 (one add-on or rebuy) 50 players for a T5,000 (one add-on or rebuy) 50 Players for a T10,000 (no add-on or rebuys)
25 Green x 400
100 Black x 500
500 Purple x 200
1000 White x 150
5000 Brown x 50
total chips = 1300
STARTING STACKS T10,000
25 Green x 16 = 400
100 Black x 16 = 1600
500 Purple x 8 = 4000
1000 White x 4 = 4000
This leaves you with enough 100 black chips to color up the 25 green chips and enough 1000 white chips to color up the 100 black chips.
You also have enough 5000 Brown chips to allow for one rebuy or add-on per person.
T5,000
25 Green x 8 = 200
100 Black x 8 = 800
500 Purple x 4 = 2000
1000 White x 2 = 2000
This leaves you with enough 100 black chips to color up the 25 green chips and enough 1000 white chips to color up the 100 black chips.
You also have enough 5000 Brown chips to allow for one rebuy or add-on per person.
T10,000 for 50 people
25 Green x 8 = 200
100 Black x 8 = 800
500 Purple x 4 = 2000
1000 White x 2 = 2000
5000 Brown x 1 = 5000
This leaves you with enough 100 black chips to color up the 25 green chips and enough 1000 white chips to color up the 100 black chips.
Here is a picture of my chips just for fun...
