Should you colour-code your daily log, or just use words?

Open most logging apps and you are asked to do two different things at once: pick a category, and write a line. It is easy to treat these as one decision — as if choosing a colour from a wheel and describing what happened are basically the same act — and then to wonder, a few weeks in, why the log feels either too thin to reread or too slow to keep up with. They are not the same act. A colour and a sentence do different jobs, and a log that only has one of them is missing half of what makes a log useful.

What a colour is actually for

A colour is not a record of an event. It is an index. Its entire value shows up later, at a distance, when you are looking at thirty or ninety days stacked in a row and trying to answer a question no single entry can answer on its own: what did this month mostly consist of? Was it heavier on work than the one before it? Did the colour that used to fill most weekday afternoons quietly stop showing up after you started the new job? None of that requires reading a single word. A calendar full of colour blocks answers it the moment you look at it, the way a chart answers a question a page of numbers technically also contains but makes you work for.

This is also why a colour has to stay cheap to assign. If choosing the right category takes longer than writing the actual line, the category has stopped doing its job and started being its own small chore — the same kind of friction that makes a running timer exhausting, just moved one step earlier in the process.

What a colour can never tell you

Two hours filed under the same colour can be nothing alike. "Work" on a day you finished something you are proud of, and "work" on a day spent in a meeting that should have been an email, look identical on the calendar and were not identical to live through. A colour preserves the category; it throws away everything that made that particular Tuesday different from every other Tuesday filed under the same one. If a month of entries is nothing but colour, rereading it tells you the shape of the month and nothing about what actually happened inside it — which is a strange thing to call a record of your own life.

What words are actually for

A line of text does the opposite job. It is not built to be scanned across ninety days; it is built to bring one specific moment back. "Told M. about the offer over the phone, she was quieter than I expected" is not something a category could ever hold, and it is exactly the kind of detail that makes a page worth opening again in a year. Words catch the things that do not fit any category at all — a name, a decision, a sentence someone said — which is most of what actually makes a day distinct from the days around it.

What words can't do at scale

The trouble with words is that they do not compress. A paragraph a day for three months is ninety paragraphs, and almost nobody actually rereads ninety paragraphs looking for a pattern — it is too much text to hold in view at once, so the pattern stays buried even though every fact needed to see it is technically sitting right there. This is the quiet reason a lot of purely written journals get abandoned: not that the writing was hard, but that the payoff for keeping it never arrived, because nothing about ninety paragraphs makes them easy to look back on as a set.

They are not competing, they are layered

Once you see it this way, the question in the title stops being a real choice. A colour is the index; the words are what the index points to. You are not picking one system over the other, you are using a fast one to find your place in a slow one — a glance at the calendar tells you which stretch of days to actually go and reread, and the words on those days tell you what a colour was always going to be too blunt to say. A log that only has colour turns into a chart of a life nobody described. A log that only has words turns into an archive nobody has the patience to search.

What this looks like day to day

In practice this is lighter than it sounds: a short line, and a category attached to it almost as an afterthought. The line does not need to justify the colour or explain itself — "watched a film with R." does not need a paragraph, and it does not need to be rated good or bad either. The colour is doing its job by simply being consistent; the line is doing its job by simply being specific. Neither one is there to keep you accountable to anything. They are there so that, later, you can look at a month from across the room, and then step close enough to read the day that turns out to matter.

TimeMap works on exactly this split: every entry is a line and a category colour, nothing more — no rating, no score, no duration attached to either one. The colour gives you the calendar's shape when you pull up a month; the line gives you back the afternoon when you tap into a single day.

If you can only manage one

Some days there is only time for one of the two, and if you have to drop something, drop the colour before the words. A colour with nothing behind it eventually stops meaning anything specific — it becomes a shape you can no longer explain, which is its own small loss. A few words with no colour attached at least still tell you what happened. The category can always be filled in later, or skipped entirely for that day; the sentence, once the moment has passed, cannot be recovered at all.
