Filing Product Range Planning: Core Colours vs Seasonal Colours

Filing product range planning starts with core colours

Filing product range planning is the process of deciding which products, colours and pack sizes to carry so stock turns over without creating dead inventory. The starting point is core colours. In Europe these are usually black, white, dark blue, red and green. They match corporate branding, school uniforms and office colour schemes. They are not exciting, but they sell every month.

At ZOKABS we see the same pattern across our export markets. Orders for black and blue lever arch files and ring binders run continuously, while bright and pastel shades come in waves tied to back-to-school seasons or special promotions. This article explains how to balance the steady core colours against the riskier seasonal shades.

How many core colours are enough

For a general office range, five to eight core colours is usually enough. Beyond that, sales split into smaller and smaller volumes, and each colour becomes harder to forecast. A typical starter set would be black, white, navy, red, green, yellow and grey. Some ranges add a clear option for users who want to see the contents.

The exact mix depends on the market. German and Nordic buyers often prefer subdued colours. Italian and Spanish buyers accept brighter shades in the core range. UK buyers expect black and blue to dominate but will stock red and green for school and home office use. We can advise on colour mix based on the destination country.

Seasonal colours drive short-term demand

Seasonal colours are shades that sell strongly for a limited period. Pastels perform well in the spring and back-to-school windows. Neon and metallic shades spike before the school year and around gift-giving seasons. Marble, wood grain and patterned finishes follow interior design trends and can run for one or two seasons before fading.

The risk with seasonal colours is over-ordering. A shade that looks fashionable in January may look dated by September. The safest approach is to place a smaller opening order and replenish quickly if it sells. This keeps dead stock low and allows the range to refresh every season.

Balancing breadth and depth

Breadth is the number of colours and styles offered. Depth is the stock held in each one. A common mistake is to launch with twenty colours and only a few cartons of each. The result is frequent stock-outs on popular shades while slow shades gather dust. A better approach is to start with a narrow core range held deeply, then add seasonal colours in smaller quantities.

For a first container order, we usually recommend holding 60 to 70 percent of the volume in core colours and 30 to 40 percent in seasonal or test colours. The seasonal portion can be adjusted once the distributor sees which shades move fastest.

Pack sizes and colour assortment

Core colours are often packed in solid cartons of one colour because the demand is steady. Seasonal colours are better packed in mixed cartons so retailers can offer a full seasonal display without committing to large quantities of each shade. A mixed carton also reduces the risk of being left with one unsold colour.

When planning pack sizes, consider the end customer. A wholesaler serving small retailers may want inner packs of five or ten pieces. A large retail chain may want display-ready cartons that go straight to the shelf. We can pack the same product in different configurations for different channels.

Coordinating across the range

A strong filing range coordinates colours across products. If the lever arch files are navy, the ring binders, box files and document wallets should also be available in navy. This lets the end user build a matching desk set. Distributors who plan the whole range together usually get better shelf presence than those who order products in isolation.

We produce coordinated ranges across lever arch files, ring binders, box files, document wallets and magazine files. Using the same colour chips across the range keeps the shades consistent. We recommend approving a master colour set before any individual product goes into production.

Managing end-of-season stock

Seasonal colours that did not sell have to be cleared. Options include bundling them with core colours, offering them as promotional packs or selling them to discount channels. The best way to reduce clearance is to start with conservative quantities and to monitor sell-through in the first few weeks.

Core colours that did not sell are a bigger problem because they do not have a natural end date. This usually means the colour was not right for the market or the price was wrong. We review core colour performance with customers during repeat order planning and adjust the mix accordingly.

Pricing and margin structure

Core colours should carry the steadiest margin because they turn over regularly. Seasonal colours can support a higher margin at launch when demand is strongest, then move to promotional pricing as the season ends. A common mistake is to price every colour the same. This leaves money on the table for trend colours and makes it harder to clear slow shades.

We help customers structure the range so that core colours fund the inventory risk of seasonal shades. The exact ratio depends on the market and the distributor's cash flow, but a healthy range usually earns a larger share of total margin from core colours while using seasonal colours to attract new buyers.

Regional colour preferences

Colour tastes vary by country more than many buyers expect. White sells strongly in medical and design-led markets. Black dominates in legal and financial sectors. Bright primary colours perform well in education markets across southern Europe and South America. Pastels are strongest in northern Europe and parts of Asia.

For a distributor selling into multiple countries, it makes sense to keep a common core and vary the seasonal colours by market. We can split production so that one country gets bright shades while another receives pastels, using the same tooling and keeping costs down.

What to specify when planning a range

The range plan should list each product type, the core colours, the seasonal colours, the expected pack size and the target market. It should also state whether colours are shared across products and whether any shade is exclusive to a season. With this plan, we can quote the range as a whole and suggest where tooling or colour changes can reduce cost.

We work with distributors to plan filing product ranges that balance predictability and freshness. The goal is to keep the core stable, refresh the seasonal offer regularly and avoid carrying colours that no longer sell.

Questions buyers ask

How often should seasonal colours change?

Most retailers update seasonal colours twice a year, for back-to-school and for the spring clean-up period. Some also add a small winter or gift range. Changing too often confuses customers; changing too rarely makes the range look tired.

Can seasonal colours become core colours?

Yes, if they sell consistently for more than one cycle. A pastel that proves popular across two back-to-school seasons can be promoted to the core range. This reduces risk because the demand has already been proven.

Do custom colours affect lead time?

Custom colours usually need a lab dip and approval, which adds a few days. Once the colour is approved and the masterbatch is recorded, repeat orders follow the normal schedule. Core colours that we produce regularly do not usually need new lab dips.
