| Direction | Reads at 16 px | Drawn from memory | Derivation | Verdict |
|---|
| 1, The gap | Partly. A ring with a notch; the 1 shrinks to a speck, so it reads as a power or reload symbol. | Easy. A ring, a 40 degree gap at 1:30, a 1 in it. The angle and the 1's exact spot are what drift. | The switch closing into the ring: the 1 is the piece that completes the circle. | The idea is clear at 180 px. Below 32 px the 1 is too small to carry it, and the 1 pokes out of the ring, which makes the mark off-centre. |
| 2, Five arcs | Partly. Ring and 1 read; the five colours blur into a pink-orange smear at 16 px and the 1 thins out. In white on the tile it is a plain ring with a 1. | Hard. Five arcs of unequal length with equal gaps, in a fixed colour order. | Five sources become one: the source colours from the Twin hero, closed into the ring of the site mark. | Says "sources" better than anything else here, but the colours only work large, and on night the blue is weak against the ground. The one-green version loses the idea and is a dashed version of the site mark. |
| 3, Points become one | No. A grey smear; at 32 px a stem with a faint flag. The dots are 1 to 2 px across at 60 px, nothing at 16. | Hard. No one can redraw 80 dots; it can only be copied. | The Twin: the stippled body, the 1 made of readings, some still arriving. | The most on-brand picture and the weakest icon. It belongs on the homepage and in motion, not in a favicon; a 1 in a ring has to carry the small sizes. |
| 4, Standing 1 | Yes. A clear figure with a dot above it, on every ground. | Easy. A 1 with a wide base and a dot. | One person: the stance is the widened foot serif, the head a dot. | Reads at once, and as the letter i, not as a 1 or a person. The widened feet help but do not break that. |
| 5, O and 1 | Partly. An oval with a heavy stroke in it, like a theta or "(1)". The cut at top and bottom is not visible at 16 px. | Hard. The cuts at top and bottom have to be exactly as wide as the 1's flag and foot. | One, the name: the 1 is the counter of the O. It is also the brand's own two letters, no ring. | Interesting at 180 px, but the cut is as wide as the 1's flag and foot, so the O falls into two brackets. See 5b. |
| 5b, O and 1, narrow cut | Partly, a little better than 5: the oval stays closed and the 1 sits in it. | Hard. Same cut, but the proportions (93 percent, small gap) are easy to get wrong. | As 5. | The better proportion: the O stays an O and the 1 still cuts it. Still dense at 32 px, and the cut shows only from 60 px up. |
| 6, L1 | Yes. The clearest at 16 px: two stems on one baseline. In one colour it reads as "L1", at 32 px white on the tile it can read as II. | Easy. An L, a 1, one shared baseline. | The name's own spelling, L1fe. Ring-free; the shared baseline serif is the join. | Strongest on legibility and on carrying the name. No ring and no switch: it says "L1" and nothing about health or sources. Next to the wordmark it repeats the L1. |
| 7, The coin | Partly. A solid disc is unmistakable; the 1 is a thin notch and the stone ring is gone. White disc on the tile reads best. | Easy. A disc, a 1 cut out, a ring. | One token of you: a coin or seal, the 1 stamped into it. | The sturdiest silhouette and the best reduction of the ring family. The ring is decoration; the 1 is light inside a big disc and wants to be larger. |
| 8, One o'clock | Partly. The dot reads; the ring is a hairline (0.6 px) and fades, and the 1 is small. | Easy. A thin ring, a dot at one o'clock, a 1. | The switch, time, one: the dot is the knob arriving, one o'clock is the 1. | Light and clear at 180 px, the weakest ring at small sizes. The dot is the only strong part below 32 px; a thicker ring would carry it. |
| 9, Horizon 1 | Partly. A striped disc; the 1 is a thin slot through the stripes, visible in white on the tile and weak on stone. | Hard. Five bands, four gaps, the 1 through all of them, and the colour order. | Five sources, one figure: the bands are the sources, the 1 is the part they share. | The strongest picture of the brand idea at 60 px and up, and it still has a 1. The colours do the work; in one green it is a plain striped disc, and the 1 is too thin to read below 32 px. |
| 10, Confluent torus | No. A swirl of colour around a green dot; no ring and no 1 remains, only a pinwheel. | Hard. Five spiral arms with a taper and a fixed profile; nobody redraws that. | Five ribbons fuse into one: the sources spiral into a single inner circle, the Twin as a centre. | Clear as a picture of convergence at 180 px, with a spiral shape of its own. It has no 1 or letter, the arms need all five colours, and at 32 px it is a ball of thread. A hero or loader shape, not an icon. |
| 11, Five-rib spindle | Yes. Five bars with a taller green one reads at 16 px and in one colour. | Easy. Five pills, heights 35, 65, 100, 65, 35. | One life made of five ribs: five bars rise to one, the middle one green. | The most robust at 16 px after 6, but it reads as an audio level meter or a signal-strength icon, not as health or a person. No 1, no ring, nothing from the name. |
