What range does the slider cover?

Minus thirty to plus thirty percent, starting at zero. Steps are single percent, so both directions cover the same amount of change.

Is this the same as vibrance in photo software?

No. Photographic vibrance protects already-saturated colours; this tool simply adds or subtracts saturation, so a vivid colour at a high setting will lose its balance.

What happens at zero?

Nothing — the result swatch shows the colour exactly as entered. That is what the default position is for, so the slider stays neutral until it is moved.

Does it preserve hue and lightness?

Yes. Only saturation changes, in either direction, so the colour stays in the same family whatever the setting.

Why does the slider start in the middle?

Zero is neutral, which keeps the colour field's own setting intact until a direction is chosen. The range runs thirty percent each way, subtracting from or adding to chroma in OKLCH, and the result is shown as a swatch without any printed reading.

The vibrance adjuster moves a colour's saturation either way from a single slider that runs from minus 30 to plus 30 percent and opens at zero.

What is Vibrance Adjuster?

The page holds a colour field, a slider labelled Saturation, and a large result swatch. The slider is the difference between this tool and the two directional ones beside it in the domain: it starts at zero, which leaves the colour unchanged, and it travels thirty percent in either direction, so the same control raises and lowers chroma.

That symmetric behaviour is what the name describes, and it is close to the sense vibrance carries in photo editing, where the adjustment is meant to be intelligent about what it touches.
Here it is not: the number is divided by a hundred and added to the colour's saturation, so a positive setting works by addition and a negative one by subtraction, with no protection for already-saturated colours and no weighting by how much chroma a colour has.
Knowing that makes the tool predictable and keeps the comparison with a photographic vibrance control honest.

The default of zero is deliberate. A slider that opens in the middle lets the colour field be used as the primary control while the slider stays neutral until it is needed, and it means the result swatch can be trusted to show exactly the colour entered until the slider moves.

Where it earns its place is in the middle of a decision rather than at the end of one. Auditioning whether a colour should carry more or less intensity is easier on one control that goes both ways than by switching between two tools, and the symmetric range makes the comparison fair — thirty percent up and thirty percent down are the same size of change by construction.

What it does not give is any reading of the result. Saturation is not printed, the amount of change is not summarised, there is no lock on lightness or hue beyond the fact that the underlying operation leaves them alone, and nothing checks whether the adjusted colour still works as text or as a surface. It is also limited to one colour with no palette view.

That neutral starting point is what makes the page useful at the start of a decision rather than at the end. Leaving the slider at zero shows the entered colour untouched, and moving it a few points either way is often enough to settle whether a candidate is too loud or too quiet for the job it will do. Read as a color intensity control rather than as an image editor, the vibrance adjuster is honest about being one number — saturation, added or subtracted, with the colour itself as the reference point between the two directions.

Limits: a single colour, a thirty percent ceiling in each direction, no relative or adaptive mode despite the name, no saved state and no export.
Read as an adjust color vibrance control rather than a photographic one, it is a clean symmetric saturation slider: one colour intensity control where the starting point is the colour itself, and the vibrance vs saturation question is answered plainly — this is saturation, by addition and subtraction.

How to use Vibrance Adjuster

Pick the colour in the field.
Move the Saturation slider negative to quieten the colour, or positive to strengthen it.
Return the slider to zero to get the entered colour back unchanged.

When to use Vibrance Adjuster vs related tools

Use this when auditioning a colour at several intensities and both directions are needed from one control. Use the saturation booster or reducer when only one direction is wanted, or the saturation explorer when the whole range should be seen at once. For a single direction the saturation booster and saturation reducer are the one-way controls, and the tone generator lays the same axis out as a ten-step strip.
