I think you have too many chips of some colors. I've found the optimum number of chips at the lower levels is 10-12. I bought tournament chips sets for up to 30 players, with 40 max. However, I rarely have over 20. I decided to double the chips for the 40-player set up (8x25; 8x100). We seem to have just as much change making with 16 and 16 as we did with 8 and 8. I frequently became the change bank because I tend to bet the highest chip value for my bet instead of a large stack of smaller ones.
My objective was to get as many of my chips in play as possible since my two primary tournament sets are only currently used about 7 times a year each. But that required a lot more work than necessary, so I went with 12 and 12. Less change made than either other way, and fewer people getting massive amounts of the smaller value chips because I think (haven't really tested this) people tend to not overuse the smaller chips.
My general rule is no more than 10 or 12 of any one color in a stack.
My best suggestion: Well, I know this is a chip site, but what I'm going to tell you is shocking. You may not believe this advice, especially on here. GET ANOTHER CHIP SET!
The set you have might be OK for a cash game, but for tournaments, it's not well suited (in my opinion). I generally agree with the "stick with standard colors" advice, even if your players don't play elsewhere. It may help to define those so I will -- white or blue = 1; red = 5; green = 25; black = 100; purple or lavender = 500; yellow or orange = 1000. After that, standard colors don't mean as much because I don't think they are standard. But you could look to this as a guide -- if the # starts with a 5, something in the red or blue range, though for 5,000 I've seen gray and brown; 25 -- generally green or blue range; 1 -- white, blue, yellow, orange. Players who play in more than one venue with undenominated chips will sometimes get confused when they have to remember that game's colors. Posting it is great, but in the heat of battle, mistakes will be made. Those who only play there will not likely understand those mistakes because they have no other frame of reference.
Get denominated chips. Colors matter a lot less with denominated chips. Even at that, I prefer standard colors. Denominated chips make a lot of things easier. That allows you to buy a set ideally suited to your needs. Just plan on buying for more players when they come, and your game may change over time. Players can be funny. Our game for years started with 10,000 (200 BB). Then I picked up players from a game where they started with 15,000 (300 BB) with blind times half the length of ours, and one re-buy was allowed, or an add-on after the break (at that point, only 15 BB). Players thought we didn't give enough in chips, so I went to 15,000, and then people started talking about the WSOP giving out 30,000 (well, selling you 30,000 in chips for $10,000). So I went to 25,000 (500 BB). Players loved the bigger stacks. Then I started doing 35,000 with a 5,000 on-time bonus, but started blinds at 50/100 (350 or 400 BB). I'm not sure what to make of players telling me they love the bigger chip stacks since I measure chip stacks according to the starting blinds. Some of those compliments come from good players who seem to be pretty good at math. I never learned the new math, so maybe I'm missing something.
Much has been written in this forum about separate chip sets for cash and tournaments. Don't mix them and you will never have the issues come up. But I still like denominated chips. So my answer, again shocking, is get a denominated tournament set AND a denominated cash set.
Two decent sets ideally suited for the needs of both games should serve you for many months, and maybe even a year or two before you realize the answer to most poker problem is more chip sets.
