Colour Management: Getting Started

Why your work looks right on your screen, wrong on your phone, and dull in print — and the small number of habits that fix it for good.

4 min read

You finish a piece. It looks right. You post it, and on your phone the shadows are crushed and the reds have gone orange. You print it, and it’s muddy. Nothing is broken — you’re just seeing what happens when nobody tells the software which colours you meant.

1. What a colour space is

A digital image stores numbers, not colours. A pixel says (220, 40, 60). A colour space is the agreement about what actual colour those numbers represent.

Change the agreement and the same numbers become a different colour. That’s the entire problem, and every symptom below is a variation of it.

The ones you’ll meet:

  • sRGB — the smallest common one and the safe default for anything going on the web. Almost every screen can display it, and anything that ignores colour management assumes it.
  • Display P3 — noticeably wider, especially in reds and greens. Standard on modern Apple displays and many phones. Colours outside sRGB genuinely exist here.
  • Adobe RGB (1998) — wider in cyans and greens; a print-oriented space with a long history in photography.
  • CMYK — not a wider space but a different model, for ink on paper. Much smaller than any of the above, which is why bright screen colours can’t be printed.

2. The single most common mistake: untagged files

An image can carry an embedded profile — a tag saying “these numbers are Display P3.” If that tag is missing, software guesses, and the near-universal guess is sRGB.

So: you work in Display P3, export without the profile, and every viewer interprets your wide-gamut numbers as sRGB. The result is colours that look oversaturated and shifted, most visibly in reds.

Always embed the profile on export. It’s a checkbox called something like “embed colour profile” or “include ICC profile”, and it costs a few kilobytes.

3. Choosing where to work

A workable default:

  • Web, social, screens: work in sRGB, export sRGB. You give up some vividness on good displays and you get predictability everywhere, which is usually the better trade.
  • Print: work in Adobe RGB or a wide space, convert to the printer’s profile at the end.
  • Wide-gamut work for good displays: work in Display P3, embed the profile, and accept that on cheap monitors it’ll render as closest-available.

The mistake to avoid is converting back and forth repeatedly. Every conversion into a smaller space permanently discards the colours that don’t fit. Work in the largest space you need, convert once, at the end.

4. Calibration, and whether you need it

Calibrating means measuring your screen with a hardware device (a colorimeter) and generating a profile that describes its actual behaviour, so the system can compensate.

Honest answer on whether it’s worth it:

  • If you print, or work for clients who print: yes. A $150 colorimeter pays for itself the first time you don’t reprint a job.
  • If your work only ever appears on screens: probably not. You cannot control what anyone else’s display does, so beyond setting a sensible brightness and using a decent monitor, calibration mostly buys you confidence rather than outcomes.
  • Either way: work in consistent, moderate room light, and turn off “night mode” / blue-light filters while colour matters. Those shift everything by design.

5. Soft proofing before you print

Soft proofing simulates, on screen, how an image will look when printed on a specific paper with a specific printer. It uses an ICC profile for that paper-and-ink combination, which print shops publish for their machines.

Turn it on and you’ll see your brightest colours go flat — that’s gamut clipping, the screen colours that ink cannot make. Better to see it now and adjust deliberately than to discover it on paper.

Two related settings to know: rendering intent (perceptual shifts everything smoothly to fit, good for photographs; relative colorimetric keeps in-gamut colours exact and clips the rest, good for graphics) and black point compensation, which you generally want on.

6. A checklist

  1. Know which space you’re working in, and don’t change it mid-project
  2. Embed the profile on every export
  3. Export sRGB for the web, always
  4. Turn off night-shift filters when judging colour
  5. Soft proof before printing, with the actual paper profile
  6. Check your export on a second device before you publish it

None of this makes your work better. It makes what other people see match what you made, which is the minimum the work deserves.
