Project managers have used a simple traffic light for decades: red, amber, green, one color to say how a piece of work is really doing. Point that same light at your own hours and a vague, forgettable day turns into something you can actually read.
RAG stands for Red, Amber, Green. It's a rating system from project and portfolio management, where each task or workstream gets a single color that answers one question: how healthy is this, honestly? Green means on track. Red means it's in trouble and needs attention. Amber is the middle — not broken, not thriving.
The genius of RAG is that it compresses a lot of judgment into one glance. A manager scanning a board of thirty items doesn't read thirty paragraphs. They see where the red is. That same compression is exactly what a personal life is missing. Most people carry a fuzzy overall impression of their week and almost no detail underneath it.
A day resists memory. By evening you remember the one great hour and the one awful one, and the other fourteen blur into "fine." A color forces a verdict while the hour is still fresh, and a verdict is what a plain time log never gives you.
There's a reason this maps so cleanly onto the way we think about hours here. Grading an hour green, amber or red is the same move as a RAG status: one honest mark, no essay required. The colors are a language for lived versus lost — time you'd choose again against time that merely happened to you. For the full method, see how to grade your hours.
The colors only work if you're consistent about what they mean. Vague definitions produce vague weeks. Here is a starting rubric you can adjust:
Two rules keep this honest. First, green is not a synonym for productive — a long lunch with someone you love is green, while an anxious hour of busywork you'll forget by Friday is amber at best. Second, unaccounted time is red, not amber. The hour you genuinely can't reconstruct is the clearest sign a day is running you, so it should show up as a warning, not a shrug.
The color people misuse is amber. In project management, amber is a genuine "watch this" signal. On a personal ledger it quietly becomes a hiding place — the color you reach for when you don't want to admit an hour was red.
A useful discipline: if you catch yourself defaulting to amber, ask whether you'd choose the hour again. If the answer is a clear no, it's red. Amber should be reserved for the honestly neutral middle — the maintenance hours a life actually requires — not for red hours wearing a softer coat. A week that is all amber is usually a week you haven't looked at closely enough.
One rated hour tells you almost nothing. The value shows up over days and weeks, when the colors form a pattern you can't argue with. This is where a month color grid earns its place: laid out side by side, your hours stop being a story you tell and start being evidence.
Three questions do most of the work once you have a week of color down:
- Where does green cluster? Almost everyone has a peak window. Protecting that block is worth more than trying to upgrade every hour.
- Where does red repeat? Look for the same drain at the same time each day. Patterns, not one-offs, are what you change.
- How much is amber that should be red? If a third of the week is neutral, some of it is probably lost time you're being generous about.
You're not hunting for a grade on yourself. You're hunting for one change worth making next week.
The trap with any self-rating system is that it's fascinating for a week and abandoned by the next. A snapshot tells you where you were; only a running record tells you whether anything changed. RAG status survives when it costs almost nothing — one honest sentence and one color per hour, then on with your day.
That two-minute pass is a habit in itself. If you'd rather score once at the end of the day than hour by hour, the end-of-day scoring ritual covers the shorter version. Either way the aim is the same: a record honest enough that you stop believing things about your time and start seeing them. Local-first and free, the colors are yours to keep — you can start rating your own hours in the app whenever you like.
Underneath the traffic light sits an older idea. The reason a lost hour is worth flagging red at all is that the hours are numbered — you are spending a life you don't get to refill. Zoom out far enough and a life is a grid of weeks, a few thousand of them for a full run. RAG status is just that grid brought down to the scale of a single afternoon: a way to notice, hour by hour, whether you're living the time or losing it. That's the whole point of the color. Not to judge the day, but to make sure you saw it.
