Chip colours are a convention, not a law
Casino chips are colour coded so that staff and players can read the value of a stack at a glance. Many casinos in the United States use broadly similar colours: white or another light colour for the lowest value, red for a middle value, green for a higher one and black for a higher one still. Even so, the colours are a convention, not a universal standard. Another country, or even another casino, may use different colours or different values for the same colour.
The reliable rule is simple: look at the number printed on the chip. Most chips are marked with their value, and the dealer will confirm anything unclear. Do not assume that a colour you know from a film or from another casino carries the same value here.
Chips you can use only at one table
Some chips are not tied to a fixed value. At certain tables, a player may be given table-specific chips, sometimes called non-negotiable chips, whose value is set by the minimum bet at that table. For example, a table with a lowest bet of a given amount may assign that value to every chip of a certain colour. These chips usually cannot be cashed or used elsewhere in the casino, so a player who leaves must exchange them for standard chips first.
Standard cash chips, by contrast, carry a printed value and can generally be used at any table or taken to the cage. Which kind a table uses depends on the casino and the jurisdiction.
How minimum bets relate to chip values
The posted minimum shapes which denominations you will see most. If the minimum is a small amount, the table is stocked with small-value chips and the dealer pays most winning bets in them. Higher minimums bring higher-value chips to the front of the tray. The details are covered in the discussion of table limits, but the practical consequence is that the chips you are given reflect the stakes of the game.
A bet that is not a multiple of the smallest chip can create a payment problem. Blackjack pays a natural at 3 to 2, so a bet that does not divide evenly can result in a payout that cannot be made with the smallest chip. As a simple illustration, if the smallest chip is worth 1 unit and a player bets 5 units, 3 to 2 pays 7.5 units, which cannot be made from 1-unit chips. The dealer then follows the house policy, which is often to round the payment in a stated direction, or the table may require bets in even amounts. The way natural payouts work, including the difference between 3 to 2 and 6 to 5, is covered in the piece on natural payouts.
What a colour up is
To “colour up” means to exchange a number of low-value chips for fewer chips of a higher value. The name comes from the chips changing colour as their value rises. The reasons are practical:
- A large pile of small chips is awkward to carry and hard to count.
- The dealer’s chip tray holds a limited number of each denomination, and low-value chips are used constantly.
- Fewer, larger chips are easier for a supervisor to check.
A colour up is usually requested by the player when leaving, but a dealer may also ask a player to colour up during a session if a stack of small chips is getting in the way of the game.
How the procedure works
Procedures vary slightly, but a typical colour up looks like this:
- The player pushes the chips to be exchanged into the betting area, or the dealer picks them up from the player’s stack.
- The dealer counts the chips aloud in plain view of the player. The count is usually made in groups, such as stacks of five, to keep it accurate.
- The dealer announces the total value and, in some houses, calls a supervisor to confirm the count if the amount is large.
- The dealer places the chips in the tray and gives back the equivalent value in higher denominations.
- If the total is not an exact multiple of the higher value, the dealer returns the remainder in smaller chips.
A quick check on the arithmetic helps. If a player has 32 chips worth 5 units each, that is 160 units. Exchanged into chips worth 25 units, that is 6 chips (150 units) with 10 units left, which the dealer would return as two 5-unit chips. The total, 150 plus 10, is 160, which matches. Always confirm that the total you hand over equals the total you receive.
Common sense for players
- Colour up in front of the dealer, not after walking away from the table.
- Do not hold up the game for a very large exchange in the middle of a hand; wait for a natural gap.
- Keep your chips visible on the table. Most casinos require chips to stay in plain sight, and stacks that are tidy are easier for everyone to count.
- Count your own chips before and after, since the count is a record both sides can agree on.
A note on money and play
Because chips feel less real than cash, it is easy to lose track of how much has been spent. A colour up can be a useful moment to pause and check the total against the session budget you set beforehand. Blackjack has a house edge, so results over time are uncertain and usually run against the player, and gambling can be harmful. If you are concerned about your play, a local support service can help.
