Your Brand Has 14 Colours. PowerPoint Gives You Six.

Brand guidelines arrive and they're gorgeous. A primary palette of four. Three secondary colours. A set of tints for backgrounds. Two more colours reserved for data visualisation, and a warm neutral somebody added later for the annual report. Fourteen colours, all documented, all lovely.

Then you open PowerPoint to build the template, and the theme gives you six accent slots.

Deciding which six, and in what order, is one of the more consequential decisions in the whole template build. It shapes every chart, every table, every default shape and every SmartArt graphic your team creates for the next five years. Most brand rollouts treat it as an afternoon's admin.

How many colours does an Office theme actually hold?

Twelve, split into three groups with very different jobs.

Four text and background colours. Dark 1, Light 1, Dark 2, Light 2. These drive body text, slide backgrounds, chart plot areas and axis labels. Office assumes the dark ones really are dark and the light ones really are light, and behaves accordingly.

Six accent colours. Accent 1 through Accent 6. These do the visible work: chart series, table styles, SmartArt, default shape fills.

Two hyperlink colours. Hyperlink and Followed Hyperlink, which default to a standard blue and a dark magenta that appear in precisely nobody's brand guidelines.

Only ten of those twelve show up in the colour picker your team sees. The two hyperlink colours do their work out of sight, which is exactly why they're the ones everyone forgets to set.

Why the order of your accents matters more than the choice

Insert a chart in PowerPoint, Word or Excel and the series are coloured in sequence: Accent 1 for the first series, Accent 2 for the second, and so on through Accent 6. Run past six series and Office loops back to Accent 1 with tints and shades applied.

That sequence is the whole game. If Accent 1 and Accent 2 are two blues of similar weight, every two-series bar chart in your business will be near enough unreadable, and somebody will fix it by hand on every single slide. If Accent 1 is your deep navy and Accent 2 is your bright coral, charts sort themselves out and nobody thinks about it again.

A few things worth knowing before you commit:

• Accent 1 is the default fill for every new shape. Draw a rectangle, get Accent 1. So Accent 1 wants to be a colour you're happy to see constantly.
• SmartArt behaves differently. It tends to skip Accent 1 in some of its colour variations, so if SmartArt features heavily in your documents, check how your palette resolves there before you finalise the order.
• Alternate light and dark down the sequence. Two adjacent accents of similar tonal value will separate poorly in a pie chart and disappear entirely in greyscale.
• Test it printed in black and white. Board packs still get printed. Somebody's chart will end up on a mono office printer and it should still make sense.
• Check it for colour vision deficiency. Around one in twelve men has some form of it. Red and green sitting next to each other in your accent order is a decision worth revisiting.

Keep the first four colours doing their actual job

There's a strong temptation to load brand colours into the four text and background slots because it feels like more brand coverage. Resist it.

Office uses those four to work out chart backgrounds and label text colours, on the assumption that the dark ones are dark and the light ones are light. Put a mid-tone brand green into Light 2 and you'll get chart labels sitting on a background with the sort of contrast ratio that fails accessibility checks and gives your compliance team a bad afternoon.

Keep them as text and background colours. Your brand belongs in the accents.

The colours you didn't choose

Office generates five tints and shades of every theme colour automatically and stacks them in a column beneath each swatch in the picker. Handy for building depth in a chart or knocking a background back. Also the source of an enormous amount of off-brand output, because those variations were produced by an algorithm rather than a designer, and a 40% tint of your brand navy isn't a brand colour.

The pale pastels at the bottom of those columns are especially popular with people building tables, and they sit nowhere in your guidelines. If your brand has approved tints, those should be defined deliberately rather than left to whatever Office generates.

This is one of the arguments for a wider palette. Give people the correct colours in the picker and they stop reaching for the approximations sitting underneath.

Theme colours versus that similar-looking blue

This is the difference that costs businesses the most and gets explained the least.

When someone picks a colour from the Theme Colours row at the top of the picker, that object is linked to the theme. Change the theme later and the object updates. When someone picks from Standard Colours, or types in a hex code, that object is now a fixed value with no relationship to anything.

Both look identical on the slide. They behave completely differently the moment you rebrand, and a rebrand is precisely when you discover how many people took the second route. A deck full of hard-coded hex values has to be corrected object by object. A deck built on theme colours updates when you swap the theme.

This is also what AI tools are reading, incidentally. A theme colour is labelled information the file carries. A hex code someone typed in is an anonymous number. If you want Copilot or any other assistant to produce on-brand output, the palette has to live in the theme where it can be recognised.

What happens when six accents aren't enough

Sometimes six is fine. A disciplined brand with a tight palette fits comfortably, and a deck restricted to five or six colours usually looks better than one attempting fourteen.

But plenty of businesses have sound reasons for a wider set. Multi-brand groups with sub-brand colours that all need to sit in one deck. Government and financial reporting where specific categories are colour-coded by convention. Data-heavy work where six series simply isn't enough and looping back into tints muddies the story.

For those cases we extend the palette. Using custom coding inside the template, we add a second row to the colour picker, taking the available brand colours up to twelve. Your team sees them in the same place they'd look for theme colours, they're labelled, and they behave consistently across the file. No hunting for hex codes in a PDF, no chart legends assembled by hand.

No setting in PowerPoint switches this on, which is why most templates don't have it. The extension is coded into the file itself, and it's one of the more satisfying things to hand over, because it removes an entire category of daily friction for the people using the template.

Worth saying plainly: we build this into a template from the start rather than adding it on afterwards. Extending a palette touches the theme, the picker, the chart defaults and the table styles all at once, and it needs testing across Windows, Mac and the web before anyone relies on it.

One theme, three applications

Worth remembering that theme colours are an Office-wide construct rather than a PowerPoint one. Define them once and the same palette is available in Word and Excel. Your report headings, your table styles, your chart series in a spreadsheet: all pulling from the same twelve slots.

Which is an argument for making these decisions across the whole template set at once rather than per application. Businesses regularly end up with a PowerPoint accent order and a Word accent order that don't match, usually because the two templates were built by different people at different times. Charts then change colour when a graph moves from a report into a deck, and everyone blames Office.

Getting it right the first time

Mapping a brand palette into an Office theme is a design decision with technical consequences, which is exactly the sort of work that falls between two stools. Brand designers hand over a palette without knowing what Accent 1 does. IT sets up the theme without knowing which colour is the primary. Somewhere in the middle, your charts turn out beige.

Do it deliberately at the start of the build and it's invisible for years afterwards, in the best sense. Every chart comes out in brand colours. Every table style works. Every shape somebody draws is already the right colour. Nobody has to think about it, which is the whole point of a template.
