Color 1 — Appetite
The simplest, “ancient” mode of assimilation. It works best on simple single-component input: one food, one task, one stream of information at a time. Complex mixes — on the plate or in the head — overload such a system. The model adds: real hunger here is not a malfunction but a working state — it is exactly on hunger that this mode gains full strength.
Left arrow (tones 1–3). Sequential: one thing whole, then the next. Finish one thing — hold a pause before taking up another; finish a chapter before opening a second book. Mixing bites on a fork and jumping between tasks goes against the grain.
Right arrow (tones 4–6). Alternating: the same simplicity, but a flexible rhythm — small portions through the day, by hunger, not by the clock. Take up a new food or task when the previous one has “let go” — both on the tongue and in the head. The main thing is not to mix at the same time; alternating is fine.
Where it slips. Carry-over is living “like everyone else”: complex mixed dishes, eating in front of a series, five parallel tabs. You notice it by the result: after such input — heaviness and a muddle in the head instead of clarity.
How to check. For two weeks simplify your input: single-component food, one product at a time (left — with a pause between, right — small portions by hunger) and one stream of information with no parallel ones. Each day briefly note how you feel after eating and how clear your head is. If there is no difference — honestly write down that there is none.
When it’s not about you. If complex mixed dishes and several parallel tasks come easily to you and your head is clear after them — this description is not yours.
Color 2 — Taste
A mode of selectivity. The body itself knows what suits it and reports through “tasty/not tasty” — about food, books, people. Pickiness here is not a whim but a working tool; eating “because it’s healthy” goes against the mechanics. The same limited set day after day is normal, not boredom.
Left arrow (tones 1–3). Open taste: preferences have to be found first — by actively trying. Ten options tried, your own found — stick to it until the body itself asks for something new. The vulnerable spot: in the trying phase it is easy to take someone else’s “but you like this” for your own.
Right arrow (tones 4–6). Closed taste: you don’t need to try — “mine/not mine” is clear at once, before tasting. The same food for weeks is normal; an instant “no” to a new dish or a new course is not stubbornness but a filter. Forcibly widening your usual set for the sake of variety goes against the mechanics.
Where it slips. Carry-over is eating and reading what is “right,” not what is tasty: by advice, by ratings, out of duty. A sure sign: the choice was not made by you — and the pleasure is zero.
How to check. For 1–2 weeks choose food and reading material strictly by your own “tasty,” ignoring “healthy” and other people’s recommendations; on the left side first give yourself a week of honest trying. Note whether appetite, pleasure and how much of what you read you actually take in change.
When it’s not about you. If you almost don’t care what you eat and what you read — “as long as there is something” — and being choosy is not your topic at all, this setting is not for you.
Color 3 — Thirst
A mode of temperature. According to the model, such a body notices whether its “input” is warm or cold — from tea to the form in which information arrives. For some, warm and “warmed-up” — processed, prepared — is more comfortable; for others, cool and “raw”: fresh unprocessed data.
Left arrow (tones 1–3). Hot. Observe how warm feels to you: hot tea instead of ice water, warm food even in summer, information “digested” by someone — notes instead of the raw stream. The model describes such a person as a transformer: you bring things to readiness yourself.
Right arrow (tones 4–6). Cold. Observe the opposite: cool drinks, food not straight off the stove, “raw” data from the primary source instead of other people’s retellings. According to the model you don’t “cook” everything alone — others around you come to readiness.
Where it slips. Carry-over is temperature “for company”: hot because everyone is drinking tea; icy because it’s summer. You notice it by a small but persistent discomfort afterwards — although “everything was as usual.”
How to check. For a week keep your own temperature mode, for a week the opposite one, all else equal. Write down whether there is a difference in comfort after eating and in how “warm” (retold) information goes in versus “raw” (primary source). No difference — record exactly that.
When it’s not about you. If you honestly don’t feel a difference between hot and cold — neither in food nor in how information is served — this color is not for you.
Color 4 — Touch
From the fourth color on, what matters is no longer the food itself but the space around you: the atmosphere of the place and the people at the moment when you eat or take in something new. The same plate and the same book go in differently in different settings. In the system this color is considered special: its skew carries over to all the other modes of digestion.
Left arrow (tones 1–3). Calm: assimilation in quiet and alone. Lunch alone without a phone or TV, study behind a closed door, one focus. Other people’s energy nearby is like noise on a channel: nothing seems to have happened, yet it didn’t get assimilated.
Right arrow (tones 4–6). Nervous: the opposite, you need movement and life around — a café, conversation, music, walking. Eating in company and working out something new in a buzzing coffee shop is a working scheme. A still, “mindful meal” in silence mutes the process for such a person instead of helping.
Where it slips. The treachery of this color is to look for the cause in the food and go through “diets” when the lever is the setting. If the foods have already been sorted through and what makes the difference is the place and the company — this is it.
How to check. For a week eat and work in your own mode (left — solitude and quiet, right — people and movement), for a week in the opposite; same food and tasks. Compare how you feel after eating and how much of what you read was assimilated.
When it’s not about you. If you feel equally good chewing and thinking in a quiet room and in a noisy café — this setting is not yours.
Color 5 — Sound
What works here is the acoustics at the moment of assimilation — specifically volume. For some a sound background is necessary, for others it is destructive. This concerns both the dinner table and the work desk: what is natural for you to eat and concentrate to — sound or silence.
Left arrow (tones 1–3). With sound. Observe how food and study go in with a sound background: music, conversations, a lively restaurant, a podcast in parallel. The model assumes that silence at the table doesn’t help such a person but gets in the way — the process seems to stop.
Right arrow (tones 4–6). In silence. The opposite pole: a quiet meal, reading without background music and chatter. A noisy feast and open space press on you; rarer but calmer is your likely format.
Where it slips. Carry-over is sound “by default”: the TV at dinner because that is how it’s done, or dead silence because it’s “more mindful.” You notice it by two extremes: either you can’t finish eating and reading calmly, or you don’t remember what you ate and read.
How to check. For a week — eating and reading in your own acoustic mode, for a week in the opposite. Record two things: comfort after eating and how much of what you read you remember the next day.
When it’s not about you. If the background changes nothing — a concert or a library, you assimilate the same — this is not your color.
Color 6 — Light
The subtlest mode: assimilation is tied to light and time of day. Such an “input” is sensitive to the lighting under which you eat and take in something new, and this sets the whole daily rhythm. The guide is not “when it’s supposed to be” but “when it is light or dark by your own measure.”
Left arrow (tones 1–3). Daylight. Observe a daytime rhythm: the main meal and the main mental work in natural light, a spot by the window, large meals before sunset. In the evening — the minimum: of both food and new input.
Right arrow (tones 4–6). Indirect light: soft and diffused — twilight, a lamp, a candle instead of a bright chandelier. A late dinner and evening work are not a failure but a possible native rhythm. Compare on yourself how food and material go in in the evening versus at noon.
Where it slips. Carry-over is living by someone else’s schedule: breakfast “because it’s morning,” bright overhead light “because that’s how it is in the office.” You notice it by a chronic feeling of “I eat and work at the wrong time.”
How to check. For two weeks shift your main meal and main mental load into your own light (left — daylight hours and the window, right — evening and soft light), without changing what you eat. Compare how you feel after eating and your productivity with your usual routine.
When it’s not about you. If the time of day and the lighting visibly affect nothing — you eat and think the same at noon and at midnight — this description didn’t fit.
