Opsino · Identify colors

What color is it?

A piece of clothing, a folder or craft paper: to name a color, aim the measurement circle at a patch with an even surface.

Main color first. Finer shade below.

In camera and photo modes, Opsino first shows a familiar main color such as red, green, blue or pink. When a more specific shade can be identified, it appears below – for example, mint green under green or magenta under red. Guidance helps you interpret uncertain results.

Choose the area that matters

Tap the circle or Measure. Opsino analyzes several recent camera frames and displays the result as your last measurement. On a patterned object, choose a single-color patch to keep neighboring colors out.

Understand the reading

Lighting and surfaces affect how a color appears to the camera. Guidance helps you know when to hold still, choose another area or try again in better light. The color name remains an estimate.

Frequently asked questions

Does Opsino identify every exact shade?

Opsino assigns a familiar color name to a surface. It does not provide certified RAL, Pantone or print color matches and does not replace professional color measurement.

Does it identify every color in the image?

Each reading concerns the selected measurement area. Aim it at the surface whose color you want to identify.

Can Opsino name two colors at once?

When two clearly distinct colors each cover enough of the measurement circle, Opsino can name both, for example “Blue with white”. Guidance still matters for unclear patterns or transitions. To identify a single detail, make the circle smaller.
