To sample a logo color in Sketchbook Pro, use the color picker (also called the eyedropper). Activate it, click a flat, solid area inside the logo, and the sampled color becomes your active color. Then open the color editor and record its numeric value, ideally the hex code, so you can rebuild the palette elsewhere. The value you get is the color of the pixels you clicked. It is not necessarily the logo's official brand color, and the rest of this guide explains how to close that gap.

What the color picker actually gives you

Sketchbook Pro is a raster painting application. Raster artwork is made of pixels, while a vector logo is made of mathematically defined paths filled with specified colors. When you sample a color in Sketchbook Pro, you read the value of one pixel or a small group of pixels. You do not read a fill value stored in a vector path.

Several factors can make a sampled pixel differ from the color the designer intended:

  • Anti-aliasing: blended pixels along edges that smooth curves and type. They mix the logo color with the background.
  • Compression artifacts: lossy formats such as JPEG shift and blotch colors, especially near edges and in flat areas.
  • Color space and profile handling: the same file can produce different numeric values depending on how it was saved and how an application interprets its embedded profile.
  • Effects in the source: gradients, textures, shadows or transparency mean there may be no single correct value to sample.

A sampled value is therefore a measurement of the artwork you have. Treat it as a working value. If an official brand specification exists, such as a style guide that lists hex, RGB, CMYK or spot-color references, that specification takes precedence over anything you sample.

Before you start

  • Use the best source file available. A large PNG or a high-resolution export beats a small JPEG or a screenshot.
  • Check your rights. Sampling a color or opening a file does not give you permission to reuse someone else's logo. A file's extension also does not prove the artwork is original, editable or vector-based.
  • Know which delivery the palette is for. Screen use needs RGB or hex values. Print use usually needs CMYK or spot-color specifications that sampling from a pixel image cannot supply on its own.
  • Confirm your version. Sketchbook Pro's interface differs between desktop, tablet and phone versions and has changed across releases. No version-specific documentation was supplied for this guide, so check tool names, shortcuts and menu locations against your installed version.

Step-by-step: sampling logo colors

  • 1. Open or import the logo image into a new canvas. If your version lets you choose a canvas size, make it large enough that the logo is not downscaled, because resampling blends pixels.
  • 2. Zoom in on the logo until you can clearly see the flat interior of each colored shape. Sample away from edges, where anti-aliasing mixes colors.
  • 3. Activate the color picker. On many desktop setups it is available as a tool in the toolbar or color area, and a modifier key held while a brush is active may switch to it temporarily. Confirm the exact control in your version.
  • 4. Check what the picker samples. If your version has an option to sample from the current layer only or from all visible layers, pick the setting that matches where the logo artwork sits, and hide any layers that could tint the result.
  • 5. Click a solid area of the first logo color. The active color swatch should update.
  • 6. Open the color editor and read the value. Record the hex code if one is shown, or the RGB values. Note which part of the logo you sampled, such as the wordmark, the icon fill or an accent stroke.
  • 7. Sample the same color in two or three other spots within the same shape. If the readings differ, the source has noise, compression or a gradient. Use the value that recurs in the cleanest area, or flag the color as uncertain.
  • 8. Repeat for every distinct color in the logo, including dark neutrals that only look black or gray. These are often not pure black.
  • 9. Optionally, save each sampled color as a swatch or custom color in Sketchbook Pro so you can compare them side by side on the canvas.

Sampling colors from type and thin details

Small lettering, thin strokes and fine lines may contain few or no pixels at full color. Every pixel can be an anti-aliased blend. If the logo includes larger elements of the same color, sample those instead. If the type is the only place a color appears, zoom in on the thickest part of the heaviest letter, such as a vertical stem, and confirm the reading at more than one point. If you cannot get a stable value, record the color as an estimate rather than a specification.

How to confirm the result

  • Consistency: repeated samples from the same flat area return the same value, or very close values.
  • Visual match: paint a block of each sampled color next to the original element at high zoom. The block should be indistinguishable from the element's interior, not its edges.
  • Completeness: every distinct color in the logo has a recorded value and a note of where it came from.
  • Cross-check: open the original source image in a second application and sample the same spots. If the values disagree, check color profile handling before trusting either reading.
  • Authority check: if brand guidelines exist, compare your values with them. Where they differ, use the documented values and treat your samples as evidence that the source file has drifted.

Turning sampled values into a usable vector palette

Sketchbook Pro does not build or edit vector paths, so the sampled palette is an input to a vector application, not a finished deliverable. In the vector application, enter each recorded hex or RGB value as a named swatch, then apply those swatches to the path fills and strokes of the reconstructed or traced logo. Assigning global or named swatches, where your vector software supports them, keeps each color consistent wherever it appears. It also lets you update the color in one place if an official value turns up later.

For export, keep screen and print values separate. Hex and RGB values sampled from a pixel image are suited to digital delivery. Converting them to CMYK changes the color, and the result depends on the conversion profile used. A sampled value also cannot tell you which spot color, if any, the brand specifies. For print-critical work, get the official print specification or have a printer proof the converted values instead of relying on a direct conversion.

If you need to export test images from Sketchbook Pro to check colors, choose a lossless format such as PNG. Saving as JPEG can introduce the same compression shifts that make sampling unreliable.

Gaps in this guide

No version-specific documentation for Sketchbook Pro was available when this guide was written. Exact tool names, keyboard shortcuts, sampling-layer options, color editor fields and swatch-saving features have not been verified for any particular release or platform. The workflow and verification checks above follow general color-sampling principles. Confirm the individual controls in your installed version before relying on them.
