# Areas and activities: colour vs. texture

> Two orthogonal axes for your day: colour for what part of life a block belongs to, texture for what kind of energy it asks. Why a planner needs both.

Published: 2026-05-29. Canonical: https://reassign.ai/resources/color-coding-your-calendar

Two blocks sit on the dial, the same size, the same hour. One is a client call. One is the deep, quiet stretch where you actually build the thing the client called about. Both are "work." On a list they'd be two identical lines. But they are not the same, and you know it in your body the moment you read them: one drains you, one feeds you, and a day that can't tell them apart can't be planned well.

So Reassign describes every block along *two* axes at once. **Area** is a colour: what part of your life this belongs to. **Activity type** is a texture: what kind of energy it asks of you. They're independent on purpose, and that independence is most of the point.

  
  *One day on the dial. Colour says which part of life a block belongs to; the fill texture says what kind of energy it asks.*

## Colour is *where in your life*

An area answers a single question: which life is this? Work, family, health, the side project, the slow domestic maintenance of being a person. You pick the colours, and once you have, the day stops being a flat sequence of obligations and becomes legible at a glance. A morning that's all one colour reads as a morning that belongs to one thing. A day streaked through with four colours reads, instantly, without counting, as [a day pulled in four directions](https://reassign.ai/resources/four-burners-theory).

This is the same argument as [why a day is round](https://reassign.ai/resources/why-a-day-is-round): you want to *see* the shape, not read it. Colour is how the dial encodes belonging. You don't tally how much of the week went to work. You look at how much of the ring is blue.

  
  *Both axes are yours to name: a colour for each area, a texture for each kind of energy.*

## Texture is *what kind of energy*

Here's where most planners stop, and where the day gets flattened. Because "work" isn't one thing. There's the heads-down build that [needs an unbroken stretch and silence](https://reassign.ai/resources/makers-schedule-vs-managers-schedule). There's the meeting that needs your face and your patience. There's the shallow admin you can do tired: the inbox, the expense report, the thing you keep not filing. Same colour, three completely different demands on you.

  
  *Same colour, opposite energy: deep work wears Flow's clean lines, the standup wears Drain's dots, both unmistakably "Work" blue.*

Activity type is the second axis: a fill pattern laid over the colour. Deep work, meetings, admin, rest, movement, errands, whatever vocabulary fits your life. It says nothing about *which* life the block belongs to and everything about *how* it will feel to be inside it.

> Colour tells you the day's allegiances. Texture tells you its weather.

## Why they have to be separate

The temptation is to collapse the two, to make "deep work" its own category and be done. But [energy cuts *across* your life](https://reassign.ai/resources/energy-based-planning), not down it. Deep work happens in your job and in your side project and, honestly, in parenting. Admin shows up in every area you have. Rest is rest whether it's a work break or a Sunday.

Fold energy into area and you lose the question you most need answered. It isn't *"[where did my time go](https://reassign.ai/resources/daily-review-planned-vs-lived)," but "what did it ask of me?"* Two orthogonal axes let you ask both at once. You can look at the dial one way and see a day that's 70% work. You can look at it another way and see a day that's 70% draining: three meetings and a pile of admin, with the one restorative block crushed into the corner. Those are different problems. A single axis can only show you one of them.

And the fix follows from the seeing. A day heavy on one texture is a day to rebalance: push a meeting, guard a stretch of deep work, let a genuine rest block keep its size instead of getting eaten. You can't protect a kind of energy you can't pick out from the rest.

## Handing the read to Claude

Because the two axes are real data on every block, they're also legible to [Claude over MCP](https://reassign.ai/mcp). When you [plan your day with Claude](https://reassign.ai/resources/planning-your-day-with-claude), it isn't guessing from titles. It reads the area and the activity type directly. "My afternoon's all meetings, find me ninety minutes of deep work before the day fills up" is a question Claude can actually answer, because the day already knows which blocks are meetings and which are the quiet kind of work. It looks first, proposes the shift, and you watch it land on the dial.

Colour and texture. Where in your life, and what kind of energy. Hold both at once and the day stops being a list of things you owe and becomes a picture you can read. And once you can read it, a thing you can fix.

## FAQ

### What is the difference between areas and activity types in Reassign?

Area is a colour that says which part of your life a block belongs to: work, family, health, the side project. Activity type is a fill pattern that says what kind of energy it asks: deep work, meetings, admin, rest. Every block carries both, and they're independent on purpose.

### Why separate life areas from energy types when categorising a day?

Because energy cuts across your life, not down it. Deep work happens in your job and your side project; admin shows up everywhere. Two axes let you see both problems: a day that's 70% work, and a day that's 70% draining. Those are different problems, and a single category system can only show you one.

### How should I categorise my day for time blocking?

Use two questions per block: which life does this belong to (area), and what will it ask of me (activity type). A handful of areas and four or five activity types cover most days. The goal is a day you can read at a glance, not a taxonomy you have to maintain.

### Can Claude read my areas and activity types?

Yes. Both axes are real data on every block, so over MCP Claude reads them directly instead of guessing from titles. Asking it to find ninety minutes of deep work before the day fills up works because the day already knows which blocks are meetings and which are the quiet kind of work.
