Portfolio Images: Keep the Colour Profile With the Picture

You finish an illustration, approve its muted greens and warm golds, and export a picture for your portfolio. On the website, something feels wrong. The tempting response is another saturation adjustment. But before changing the artwork, check how its colour information travelled.

Colour is part of the work you are presenting. A useful export routine should preserve your intended appearance as far as the destination allows, while keeping the original available for other uses. That calls for a few deliberate decisions about profiles, conversion and checking. It does not require turning every portfolio update into a laboratory exercise.

A profile tells software how to interpret the numbers

An image’s colour profile gives meaning to its colour values. Adobe’s guide to changing document profiles, updated on 6 October 2026, distinguishes two operations that sound deceptively similar. Assigning a profile leaves the colour numbers unchanged but changes their interpretation. Converting changes the numbers to preserve appearance when moving into another colour space.

Those are different interventions. If you are preparing a correctly profiled image for a new destination, do not substitute assigning the destination profile for the intended conversion. If the source profile is missing or uncertain, establish the file’s history before treating a plausible-looking assignment as a confirmed repair.

Choose an output before choosing its settings

For broadly compatible web images, Adobe’s online-viewing guidance, updated on 30 September 2026, recommends sRGB. Its instructions for converting an existing image use Edit > Convert to Profile, with sRGB IEC61966-2.1 as the destination and a preview before applying the change.

This is a practical starting point for an ordinary portfolio, rather than a claim that every publishing workflow must use identical settings. If a client or platform specifies another supported output, follow that documented requirement and check the result in its intended environment.

Keep your editable master separate. Adobe’s print-profile guidance, updated on 4 October 2026, explains that working spaces offer different colour ranges; sRGB cannot represent some saturated colours available in wider spaces. A web export therefore should not become your only surviving version for future print work.

Conversion and embedding are separate choices

Adobe’s Export As reference, updated on 23 February 2026, lists conversion to sRGB and the option to embed the colour profile under colour-space settings. Embedding carries the profile with the exported image. Conversion prepares the colour values for the chosen space. Check both decisions in your export route instead of assuming that selecting JPEG settles them.

For a small portfolio collection, keep a short record beside the exports:

• Source: which approved master produced this picture?
• Destination: which portfolio, gallery or client delivery is it for?
• Colour: what source profile was present, what conversion was used, and was the destination profile embedded?
• Version: which exported file was checked and then uploaded?

This record can be a few lines in a project note. Its purpose is to make a repeatable delivery decision visible, particularly when someone else prepares the next update.

Follow one picture through the journey

Consider a hypothetical illustrator whose portfolio includes a teal botanical cover. The approved master has a known embedded profile. She makes an sRGB web copy, embeds its profile, then opens that exported file in her editor. Next, she checks the uploaded image in the portfolio page on the same computer.

If the first visible change appears in the export, she has narrowed the investigation to that stage. If the export looks acceptable but the page differs, she investigates the page’s delivered image and viewing environment. Neither observation alone establishes the cause. It gives her a more useful question than “Why are my colours bad?”

Where the site permits downloading its displayed image, compare that file’s profile and appearance with the uploaded export. Record what you actually find. Do not assume that every website preserves, removes or converts profiles in the same way.

The point of this exercise is to locate a change before compensating for it. Adding saturation to the master because one preview looks dull creates a new creative decision; keep that decision separate from diagnosing the delivery process.

A second screen is a check, not the reference for every edit

The International Color Consortium’s display-calibration guidance explains that calibration and profiling work together: the display is adjusted towards a chosen behaviour, and a profile communicates its colour characteristics. An image profile and a display profile therefore have different roles. Embedding the former does not calibrate the viewer’s screen.

Review a representative picture on another device to notice substantial surprises. Treat a difference as an observation to investigate, rather than immediately editing the master to match whichever screen you checked last. A second device is useful evidence about the viewing experience, but it is not automatically a more accurate reference.

For work where colour accuracy is central, such as approving a specific product shade, agree a suitable reference and review process with the recipient. A casual comparison between two unverified screens cannot establish which one represents that shade accurately.

Give AI a bounded job in the handover

If you use an AI assistant to organise your publishing work, ask it to turn settings you have actually checked into a concise export checklist. Supply the application, intended destination, source-profile information and export choices. Require it to leave unknown settings marked for checking.

Do not ask a verbal description of the picture to establish its embedded profile. Likewise, an attractive generated replacement would create different artwork rather than confirm that the approved file survived export. The useful contribution here is organising the work around evidence you can inspect.

Before this stage, decide which images deserve a place in the portfolio. MaryChuks.com’s guide to selecting and sequencing a photo story offers a practical way to make that editorial choice. Then export the selected work with the same care you gave its arrangement.

Make the delivery explainable

Finish with an approved master, a clearly identified web copy and a note of the settings used. Check the exported file and the published page before calling the delivery complete. Keep any intentional colour edits identifiable as edits.

You cannot control every screen that will display your work. You can give the picture a defined colour interpretation, prepare it for a known destination and preserve enough context to investigate a mismatch. That is a realistic standard for presenting creative work with care.
