I’ve become a big fan of colour-coded calendars over the years. Not because they look neat. Not because they make me feel organised. And certainly not because I enjoy spending time categorising appointments.
I like them because they tell the truth.
The reality is that most of us have a very different perception of how we spend our time compared to what actually happens. Ask someone where their week went and you’ll usually get an answer based on memory, emotion or whatever felt busiest. Open a colour-coded calendar and suddenly the conversation changes.
The evidence is right there in front of you.
And sometimes it’s not what you expected to see.
Busy Doesn’t Mean Progress
One of the first things a colour-coded calendar exposes is whether you’re actually moving forward or simply staying occupied.
I’ve seen weeks where the calendar looked completely full. Every day packed from morning until late afternoon. At first glance it felt productive.
Then I looked at the colours.
Almost every block was internal meetings.
Status updates. Catch-ups. Reviews. Discussions about discussions.
There wasn’t much time allocated to activities that improved the business, created something new, built a process, documented knowledge or generated future value.
That’s a confronting realisation.
Many business owners and IT professionals spend their entire week responding to what’s already happening instead of creating what happens next. A simple colour system makes that visible very quickly.
The calendar doesn’t care how important the meeting felt at the time. It simply shows where the hours went.
Seeing the Cost of Context Switching
Another thing colour coding reveals is how fragmented your day has become.
You start with a customer conversation. Then jump into Outlook to clear email. Then sit through a Teams meeting. Then back to customer work. Then another meeting. Then more email.
By lunchtime you’ve changed focus so many times that it feels like you’ve been running all morning but haven’t actually completed anything meaningful.
I see this regularly with MSPs and small business teams.
The work itself isn’t necessarily the problem. It’s the constant switching between different types of work.
When each category has its own colour, the pattern becomes obvious. Instead of solid blocks of concentrated effort, the calendar looks like confetti scattered across the day.
Once you can see it, it’s much easier to fix.
You begin grouping similar activities together. Customer calls sit together. Administration sits together. Internal meetings get pushed into dedicated windows.
The day starts working for you instead of against you.
Your Best Hours Matter Most
The biggest lesson I keep coming back to is how valuable the first few hours of the day really are.
That’s when my thinking is usually at its sharpest.
It’s when I want to write, plan, create content, build presentations or work with Microsoft 365 Copilot to develop ideas and explore new approaches. Whether I’m using Copilot in Word to draft an article or reviewing strategy notes from a Teams meeting, those activities benefit from clear thinking and uninterrupted attention.
Yet many calendars tell a different story.
The most productive hours are often handed over to routine meetings, administrative work or conversations that could easily happen later.
When I review a colour-coded calendar, that issue jumps out immediately.
The colours show whether those high-energy hours are being invested or simply consumed.
That’s an important distinction.
The Colours Never Argue
What I like most about colour coding is its honesty.
It removes assumptions.
It removes excuses.
It removes that comfortable story we tell ourselves about where our time goes.
Open your calendar and look at the next seven days.
Which colour dominates?
Customer work? Internal meetings? Administration? Personal development? Strategic planning?
Whatever colour appears most often is receiving the largest investment of your time.
And over the long term, that’s probably where your business, career and attention are heading as well.
The colours won’t tell you what to do.
But they will show you the truth.
And that’s usually the first step towards making better decisions.
