I Have a 500-Piece Wedding Order in a Custom Colour — How Much Extra Dye and Wax Should I Allow for Colour-Development Trials?

The short answer: trial tins, check pucks, and dye bought twice

A custom wedding colour is a target the client sets — a swatch from the invitation, a fabric sample, a photograph of the décor. Getting there takes trials, and the trials consume real materials: wax, fragrance, wicks and containers as well as dye, because a colour judged in a bare wax puck will not look the same in the finished candle. Fragrance oils carry their own tint and can shift a shade; the depth of the pour and the finish of the surface change how a colour reads; and soy-based waxes commonly look different warm, freshly set and fully cured. So the trial candle has to be the real candle, made the real way, in small numbers.

CSI does not publish dye doses — how much of each liquid dye or chip colours a kilo of wax — and the product pages are the place to start. That has two consequences for the order. First, the dye for the trials is bought in the smallest listed packs, because you do not yet know how much you will use. Second, the dye for production is bought after the client approves a colour, in a quantity you calculate from the dose your trials settled on. Between those two purchases sit the extra wax and materials for the trials themselves and for a small check pour at the start of every production batch. On this order that is 21 trial tins and 9 check pucks: 1.89 kg of wax, roughly 4.5% more than production alone.

The production BOM before any colour allowance

The example is 500 wedding favours in Golden Aluminium Tins, one of only two CSI containers with a published fill — 85 g. In Premium Coconut Soy Wax CSI 468 with Raat Ki Rani (Night-Blooming Jasmine) at 8%, each tin holds 6.8 g of oil and 78.2 g of wax. CSI's product page for CSI 468 states a melting point of 50–53°C, pour at 58–60°C and fragrance load up to 13%. A 3% reject allowance (a labelled working assumption) makes 500 saleable favours into 516 production tins. In a tin, the colour shows on the top surface; in clear glass it would show through the wall as well, which makes trials more demanding still.

That last row is the reason this post exists. Every other line can be calculated today; the dye line cannot, and neither can the extra wax for getting there unless you plan the trials. The next two sections do that — first the trial rounds, then the batch check that keeps 500 tins the same colour.

Planning the colour trials as candles, not as drops

Twenty-one tins sounds like a lot for a 500-piece order. It is 4.2% of the order, and each tin carries about ₹134.40 of CSI material, so the whole trial programme costs roughly ₹2,822.36 in wax, oil, wicks, tins and stickers before dye. The alternative — approving from a puck, then discovering in the first production batch that the oil has pulled the shade warmer — costs a remelt of a 5 kg batch.

Which CSI dyes you can actually trial with this week

CSI's liquid dyes and dye chips are listed in a handful of colours, and two of the liquids — green and yellow — are out of stock on the pull; green chips are out of stock too, and black chips had a single unit in stock, so do not plan around them. For a custom colour that needs a warm yellow component, the in-stock route is yellow candle dye chips at ₹250.00. For a dusty rose — a common wedding request, used here as the example — the route is a red base with a brown toner. Mica (white or green, from ₹57.82 for 10 g) is commonly cautioned against inside the melt pool because pigments can clog a wick; many makers keep it to surface decoration, so test before using it in a burning candle.

For the trials, buy the smallest pack of each colour you will actually use: here red and brown liquid at ₹236.00 each and a yellow chip at ₹250.00 in case the client's swatch is warmer than expected — ₹722.00. Brown liquid also shows a 100 g listing whose price looks like a listing error, so we do not quote it and you should not plan around it. Confirm on WhatsApp if you need a larger brown pack.

Turning the approved trial into a production dye quantity

When the client signs off, your round 3 tin gives you a dose in grams of dye per kilo of wax. The production quantity is then simple arithmetic: dose × production wax (plus the check pucks). On this order production wax is 41.97 kg and the pucks add 0.18 kg, so every 0.1 g/kg of your measured dose means 4.21 g of dye for the whole run. The table shows the arithmetic at a few round values. They are columns for multiplication, not recommended doses — your number comes from your trial tin.

Two rules keep this honest. If your colour uses two dyes, do the sum for each one separately with its own dose. And buy production dye with a margin for the batch-matching adjustments described next — a labelled 10–20% is a reasonable working buffer for dye alone, because small corrections are part of the method, and dye is a small cost beside the wax it colours.

Keeping 500 tins the same colour: the check puck

A 500-tin order is poured in batches. At a labelled example of about 5 kg of wax per melt, production is 9 batches. Each batch is coloured from the dose, and each batch can drift: a slightly different weighing, a different melt temperature, a fresh bottle. The cheapest insurance is a check puck — 20 g poured from every coloured batch before any tin is filled, cooled quickly and set beside the kept reference tin. If it matches, pour. If it is light, add a weighed correction and pour another puck. That is 9 × 20 g = 180 g of wax over the order, and it is the line most often forgotten.

In packs, the colour allowance moves the CSI 468 order from 4 × 10 kg + 2 × 1 kg (₹26,780.00) to 4 × 10 kg + 4 × 1 kg (₹28,080.00) — ₹1,300.00 of wax for a colour the client actually approved. The oil, wicks, stickers and tins for the 21 trial tins are in the shopping list below; the pucks need wax and dye only.

The priced CSI shopping list

Two pricing notes. CSI 468 is ₹650.00 a kilo at 1 kg and ₹637.00 at 5 and 10 kg, so the bulk of the wax is in 10 kg bags with 1 kg top-ups. Raat Ki Rani is ₹6.77 a gram at 500 g and 1 kg, ₹7.00 at 100 g and ₹8.67 at 15 g; the list uses the cheapest cover. The tins are ₹30.00 each in the pack of 12, so 537 tins round to 540.

Buy now, buy after the client approves the colour

Colour trials split the order cleanly. Now: enough wax, oil, tins, wicks and stickers for 21 trial tins, plus the trial dyes — and the wick test if the wick is not settled (the single-wick post covers that). After approval: the production wax and oil balance, the remaining tins, the production wick pack and the production dye in one lot. The tins can come forward if you prefer — they are fixed by the design and do not age — but the dye must wait, because its quantity does not exist until the trials finish.

The rest of the 500–1,000 candle cluster

Colour is one allowance on a large order. Jar breakage and wick allowances size two more; the new-fragrance post applies the same buy-after-approval logic to oil; emergency remakes covers replacement stock on a deadline; the buffer-logic post explains why dye, wax and glass buffers differ; and the procurement sheet brings them together. For a smaller pilot of the same idea, the pastel-pink rose post tests load, dye and wick together.
